Question

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

Answer 1

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.

Answer 2

Answer:

A. 88 square units.

Step-by-step 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.
