Question

What is the surface area of this design

Answer 1

Answer:

The surface area is equal to $384\ in^{2}$

Step-by-step explanation:

we know that

The surface area of a cube is equal to

$SA=6b^{2}$

where

b is the length side of a cube

In this problem we have

$b=8\ in$

substitute

$SA=6(8^{2})=384\ in^{2}$

Answer 2

384 8x8=64 64x2=128 128x3=384
