Question

What is the surface of the triangular prism?

Answer 1

2 376 ft²

Explanation:

the surface of the triangular prism =

= 2 × (area of the base) + (lateral area)

= 2 × [(24×9)÷2] + (24+15+15)×40

= 2 376

Answer 2

2376 square feet

Explanation:

40 x 15 = 600

40 x 24 = 960

1/2 x (24 x 9) = 108

600 + 600 + 960 + 108 + 108 = 2376
