cubic feet

Answer 1

Explanation:

1.) 2x2x3x2x5x2=240 surface area A

2.)1x2x2x3x7x2=168 surface area B

1.) 2x3x5= 30 volume of A

2.) 1x3x7= 21 volume of B

Hope this helped! I also hope I didn't get this wrong. I did it on mobymax

Answer 2

Explanation:

The formula to determine the surface area of a rectangular prism is expressed as

A = 2WL + 2LH + 2HW

where

W is the width of the rectangular prism

L is the length of the rectangular prism.

H is the height of the rectangular prism.

1) The dimensions of rectangular prism A is 6 feet × 3 feet × 2 feet.

The surface area of A is

(2×6×3) + (2×3×2) + (2×6×2) = 36 + 12 + 24 = 76 square feet

2) The dimensions of rectangular prism B

B is 2 feet × 4 feet × 4 feet.

The surface area of B is

(2×2×4) + (2×4×4) + (2×2×4) = 16 + 32 + 16 = 64 square feet

The volume of a rectangular prism is expressed as L×W ×H

3) the volume of rectangular prism A is 6×3×2 = 36 cubic feet

4) the volume of rectangular prism B is 2×4×4 = 32 cubic feet
