Rectangular prism a is 6 feet × 3 feet × 2 feet. rectangular prism b is 2 feet × 4 feet × 4 feet. what is the surface area of a? square feet what is the surface area of b? square feet what is the volume of a? cubic feet what is the volume of b? cubic feet

Step-by-step explanation:

The formula to determine the surface area of a rectangular prism 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
