Answer:

Surface Area = 2lw + 2lh + 2hw  =  2(lw+lh + hw) = 2(12x8 + 12x4 + 4x8)  = 2(96+48+32) = 2(176) = 352 square inches

The surface area of the is mathematically given as

A= 1048in^2

What is the Surface Area?

Question Parameter(s):

Generally, the equation for the Surface area   is mathematically given as

A = 2(lw + wh +lh)

Therefore

A = 2(20(8) + 8(13) +20(13))

A = 2(160+104+260)

A= 1048in^2

In conclusion, the Surface area is

A= 1048in^2
