Which option expresses the surface area of a rectangular prism with the following dimensions: length = 4, width = 3, height = 6 ?

A: (4 × 3 + 4 × 6 + 3 × 6)

B: 2 (4 × 3 + 4 × 6 + 3 × 6)

C: 2 ( 4 × 3 × 6)

D: 2 ( 4 + 3 + 6)

i think it's b right

its B

i think the answer is

E: None of the above. The surface area is actually 42 jokes about rectangles and prisms. Just kidding! It's option A: (4 × 3 + 4 × 6 + 3 × 6).

To find the surface area of a rectangular prism, you need to calculate the sum of the areas of all its faces.

A rectangular prism has 6 faces - 2 rectangular faces on the top and bottom, and 4 rectangular faces on the sides.

To calculate the area of each face, you need to multiply the length by the width.

For the given dimensions:
length = 4
width = 3
height = 6

To find the surface area, you need to calculate the area of each face and sum them up.

Let's go through each option and determine which one correctly expresses the surface area:

Option A: (4 × 3 + 4 × 6 + 3 × 6)
This option calculates the area of each face and sums them up correctly.

Option B: 2 (4 × 3 + 4 × 6 + 3 × 6)
This option multiplies the surface area calculated in Option A by 2, which is correct since you need to account for both the top and bottom faces.

Option C: 2 (4 × 3 × 6)
This option only multiplies the length, width, and height but does not calculate the areas of each face correctly. It is not the correct formula for finding the surface area of a rectangular prism.

Option D: 2 (4 + 3 + 6)
This option incorrectly adds the dimensions together instead of calculating the areas of each face. It is not the correct formula for finding the surface area of a rectangular prism.

Based on the explanations above, the correct option is B: 2 (4 × 3 + 4 × 6 + 3 × 6), which correctly expresses the surface area of the rectangular prism.

I think the answer is A
