What is the surface area of a right rectangular prism with a width of 12 inches, a length of 6 inches, and a height of 8 inches?
a.144 in2
b.288 in2
c.432 in2
d.576 in2

Option (c) is correct.

Surface area of a right rectangular prism is 432 inches²

Step-by-step explanation:

  Given :   A right rectangular prism with a width of 12 inches, a length of 6 inches, and a height of 8 inches.

We have to determine the surface area of a right rectangular prism.  

Surface area of a right rectangular prism is given as 2(lw + wh + hl)

Where l = length

w is width

h is height

for the given right rectangular prism with a width = 12 inches,

length = 6 inches,

height = 8 inches.

Substitute, we have,

Surface area of a right rectangular prism = 2(6 × 12 + 6 × 8 + 8 × 12)

Simplify, we have,

Surface area of a right rectangular prism = 432 inches²
