Question

9. 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?

Answer 1

Surface area is 300 in Squared

Step-by-step explanation:

2(lw + wh + hl) = rectangular Prism Formula

Length- 12

Width- 9

Height- 2

So just Substitute the values.

2( 12 x 9+ 9 x2 + 12 x 2) = ?

2(108 +18+ 24)

2 x 150

= 300

Answer 2

The surface area of the prism is 300 square inches.

Step-by-step explanation:

To find the surface area of a right rectangular prism, we can use the formula S = 2(lw + wh + hl), where S is the surface area, l is the length, w is the width, and h is the height.

Plugging in the given values: S = 2(12 * 9 + 9 * 2 + 2 * 12) = 2(108 + 18 + 24) = 2(150) = 300 square inches.

Therefore, the surface area of the prism is 300 square inches.
