Question

What is the surface area of the triangular prism?

Answer 1

2,376 ft²

Explanation:

surface area = bh + L(s1 + s2 + s3)

where b = 24 ft.

h = 9 ft.

s1 = 15 ft.

s2 = 15 ft.

s3 = 24 ft.

L = 40 ft.

plugin values into the formula:

A = 24*9 + 40(15 + 15 + 24)

= 216 + 40(54)

= 2,376 ft²
