Question

Find the total surface area of rectangular prism with l=6, w=4, h=2

Answer 1

A. 88 square units.

Explanation:

Volume formula:

↓

`V=L*W*H`

`6*4*2=48`

`L*H*2`

`6*2*2=24`

`W*H*2`

`4*2*2=16`

Add the numbers from left to right.

48+24=72

72+16=88

88 is the correct answer.

Answer 2

SA = (l x w x 2) + (l x h x 2) + (w x h x 2)

SA = (6 x 4 x 2) + (6 x 2 x 2) + (4 x 2 x 2)

SA = 48 + 24 + 16

SA = 88

The answer is 88 square units.
