Answer:
Option (c) is correct.
Surface area of a right rectangular prism is 432 inches²
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
