Okay, I need to solve this problem about the surface area and volume of a rectangular prism and a cube. First, I need to carefully look at the problem to make sure I understand the requirements for each part.

The problem asks to calculate the surface area and volume of two shapes separately. The first shape is a rectangular prism, and the second is a cube. The units are all in centimeters, and each question is worth 6 points, for a total of 12 points. This looks like a math homework problem, possibly from elementary or middle school geometry.

First, I need to recall the formulas for the surface area and volume of a rectangular prism and a cube. For a rectangular prism, the formula for surface area is: \( 2(ab + bc + ac) \), where a, b, and c are the length, width, and height, respectively. The volume is \( abc \). For a cube, since all side lengths are equal, the surface area is \( 6a^2 \), and the volume is \( a^3 \).

Now, let's look at the first shape, a rectangular prism with given dimensions of length 4 cm, width 3 cm, and height 2 cm. I need to calculate its surface area first. Plugging the values into the formula:

Surface Area = \( 2(4×3 + 3×2 + 4×2) \)
        = \( 2(12 + 6 + 8) \)
        = \( 2×26 \)
        = 52 cm²

Next is the volume, again plugging in the values:

Volume = \( 4×3×2 \)
      = 24 cm³

Then, for the second shape, a cube with a side length of 3 cm. The surface area is calculated as follows:

Surface Area = \( 6×3^2 \)
        = \( 6×9 \)
        = 54 cm²

And the volume is:

Volume = \( 3^3 \)
      = 27 cm³

However, I need to check for any potential mistakes. For example, in calculating the surface area of the rectangular prism, did I miscalculate the area of any face? Or did I make a mistake in the multiplication?

For instance, the three different faces of the rectangular prism are 4×3, 3×2, and 4×2. The areas of these faces are 12, 6, and 8. Adding them up gives 26, and multiplying by 2 gives 52, which should be correct. For the volume, 4×3=12, and then multiplying by 2 is 24, which is also correct.

For the cube, each face is 3×3=9, and with six faces, the total is 54. The volume is 3×3×3=27, which is also correct.

So the final answers should be:

1. The surface area of the rectangular prism is 52 square centimeters, and the volume is 24 cubic centimeters.
2. The surface area of the cube is 54 square centimeters, and the volume is 27 cubic centimeters.

However, I need to confirm if there is any other hidden information or potential traps in the figures in the problem. For example, sometimes problems might include dashed lines or shaded areas, but in this case, the rectangular prism and cube in the image look standard, with no special markings. Therefore, I believe my calculations are correct.

Okay, I need to solve this problem about the surface area and volume of a rectangular prism and a cube. First, I need to carefully look at the problem to make sure I understand the requirements for each part.

The problem asks to calculate the surface area and volume of two shapes separately. The first shape is a rectangular prism, and the second is a cube. The units are all in centimeters, and each question is worth 6 points, for a total of 12 points. This looks like a math homework problem, possibly from elementary or middle school geometry.

First, I need to recall the formulas for the surface area and volume of a rectangular prism and a cube. For a rectangular prism, the formula for surface area is: \( Area = 2(ab + bc + ac) \), where a, b, and c are the length, width, and height, respectively. The volume is: \( Volume = abc \). For a cube, since all side lengths are equal, the surface area is: \( Area = 6a^2 \), and the volume is: \( Volume = a^3 \).

Now, let's look at the first shape, a rectangular prism with given dimensions of length 4 cm, width 3 cm, and height 2 cm. I need to first confirm that these values correspond correctly to the variables in the formula. Usually, the three dimensions of a rectangular prism can be named arbitrarily, but for convenience, we can consider the longest side as the length, the middle one as the width, and the shortest as the height. However, in this case, the problem has clearly labeled the lengths of each side, so I can use them directly.

Next, I'll calculate the surface area of the first rectangular prism. Plugging the values into the formula:

\( Area = 2(4×3 + 3×2 + 4×2) \)

First, calculate each term inside the parentheses:

\( 4×3 = 12 \)
\( 3×2 = 6 \)
\( 4×2 = 8 \)

Then, add these results together:

\( 12 + 6 + 8 = 26 \)

And multiply by 2:

\( 2 × 26 = 52 \)

So, the surface area of the first rectangular prism is 52 square centimeters.

Next, calculate the volume:

\( Volume = 4 × 3 × 2 = 24 \)

So, the volume is 24 cubic centimeters.

Now, let's look at the second shape, a cube with all side lengths of 3 cm. Therefore, the surface area calculation is:

\( Area = 6 × 3^2 = 6 × 9 = 54 \)

And the volume is:

\( Volume = 3^3 = 27 \)

So, the surface area of the cube is 54 square centimeters, and the volume is 27 cubic centimeters.

During the calculation, I need to pay attention to the consistency of units. The unit given in the problem is centimeters, so the final results should be in square centimeters and cubic centimeters. Also, I need to ensure there are no calculation errors, such as the order of multiplication and addition, especially when calculating the surface area of the rectangular prism, where it's easy to miss a term or make a calculation mistake.

Additionally, I'll check for any other possible misunderstandings, such as whether the length, width, and height are correctly identified. But in this problem, since the lengths of each side are clearly labeled, this should not be an issue. Also, for the cube, all side lengths are equal, so there's no complexity from different side lengths.

To summarize, the surface area of the first rectangular prism is 52 square centimeters, and its volume is 24 cubic centimeters. The surface area of the second cube is 54 square centimeters, and its volume is 27 cubic centimeters.

Hmm, I need to solve this problem, which is to calculate the surface area and volume of two shapes. First, I need to carefully examine the image provided in the problem. The first shape is a rectangular prism, and the second is a cube. The problem asks to calculate their surface area and volume separately, with units in centimeters.

Let's look at the first shape, the rectangular prism. Its dimensions should be length, width, and height. According to the labels on the image, the length is 4 cm, the width is 3 cm, and the height is 2 cm. Right? I remember the formula for the surface area of a rectangular prism is 2 times (length × width + length × height + width × height). And the volume is length times width times height. Let me double-check if the formula is correct. Yes, the surface area is indeed the sum of the areas of the six faces, and since opposite faces have equal areas, this formula is correct.

So, plugging in the values, the surface area should be 2×(4×3 + 4×2 + 3×2). First, calculate the terms inside the parentheses: 4×3=12, 4×2=8, 3×2=6. Adding them up gives 12+8+6=26. Then multiplying by 2 gives 52 square centimeters. For the volume, 4×3×2=24 cubic centimeters. This part should be correct.

Next is the second shape, the cube. All its side lengths are 3 cm. The surface area of a cube is 6 times the square of the side length, because it has six identical square faces. The volume is the cube of the side length. So the surface area should be 6×3²=6×9=54 square centimeters. The volume is 3³=27 cubic centimeters. I need to pay attention to the units here. The problem states the unit is cm, so the results should be written in square centimeters and cubic centimeters.

However, I should double-check if I made any mistakes. For example, are the sides of the rectangular prism correctly identified? In the image, the length of the rectangular prism does look longer than its width, so length is 4, width is 3, and height is 2. For the cube, all three dimensions are 3, which is fine. Did I make any calculation errors? For example, in the surface area calculation for the rectangular prism, are the products correct, and is the addition correct? For instance, 4×3=12, 4×2=8, 3×2=6, adding up to 26, and multiplying by 2 is 52, which is correct. The volume 4×3×2=24 is also correct. For the cube, the surface area 6×9=54 and volume 27 are also correct.

One thing to note is the units. The problem clearly states the unit is cm, so I should add the correct unit symbols to the answers. Also, the problem states that each question is worth 6 points, for a total of 12 points, but there are only two questions, so each is worth 6 points. This doesn't affect the calculation process, but it's a reminder not to miss any steps or units.

To summarize, the surface area of the first shape is 52 square centimeters, and its volume is 24 cubic centimeters; the surface area of the second shape is 54 square centimeters, and its volume is 27 cubic centimeters. That should be it.
