Question

Use the formula SA=2(lw)+2(wh)+2(lh) to find the surface area for a rectangular prism with the length l of 2.8, a width w of 1.19 yd, and a height h of 6 yd

Answer 1

Explanation:

The formula for the surface area of a rectangular prism is SA = 2(lw) + 2(wh) + 2(lh), where l is the length, w is the width, and h is the height.

Given:

l = 2.8 yards

w = 1.19 yards

h = 6 yards

Plugging in the values:

SA = 2(2.8 * 1.19) + 2(1.19 * 6) + 2(2.8 * 6)

Simplifying and converting units to square yards:

SA = 2(3.32) + 2(7.14) + 2(16.8)

SA = 6.64 + 14.28 + 33.6

SA = 54.52 square yards.

The surface area of the rectangular prism is 54.52 square yards.
