The surface area S , of a right rectangular prism with length l , width w ,and height h can be found using the formula below

S=2(lw + wh + hl)

What is the surface area in square inches of a prism with a length of 12 inches a width of 9 inches, and a height of 2 inches?

First, replace all variables with the given values.
12(9) + 9(2) + 2(12)
This should then equal 150, then the formula says to multiply this answer by 2. Doing so, should give a final answer of 300.

The surface area of the prism is 300 in².

What is a prism?

A prism is a 3- dimensional shape with two identical shapes facing each other.

To calculate the surface area of the prism, we substitute the values into the equation of the surface area of a prism given in the question above.

Formula:

S = 2(lw+wh+hl).............. Equation 1

From the question,

Given:

l = 12 inches
w = 9 inches
h = 2 inches

Substitute these values into equation 1

S = 2[(12×9)+(9×2)+(12×2)]
S = 2(108+18+24)
S = 300 in²

Hence, the surface area of the prism is 300 in²
