Find the surface area of the triangular prism

608 ft²

Step-by-step explanation:

1) Find the area of the bases

where b is the base length and h is the height

Plug in b and h

Multiply the answer by 2 (because there are 2 bases)

A=96

Therefore, the area of the two bases is 96 ft².

2) Find the area of the two sides facing up

where l is the length and w is the width

Plug in l and w

Multiply the answer by 2 (because there are 2 sides)

A=320

Therefore, the area of these two sides is 320 ft².

3) Find the area of the bottom side

where l is the length and w is the width

Plug in l and w

Therefore, the area of this side is 192 ft².

4) Add all the areas together

96 ft² + 320 ft² + 192 ft²

= 608 ft²

Therefore, the surface area of the triangular prism is 608 ft².

I hope this helps!
