What is the surface area of the triangular prism?

Given:

The base of the triangle is b = 3 feet.

The height of the triangle is h = 4 feet.

The other side of the triangle is 5 feet.

The height of the triangular prism is 20 feet.

We need to determine the surface area of the triangular prism.

Surface area of the triangular prism:

The surface area of the triangular prism is given by the formula,

where b is the base of the triangle,

h is the height of the triangle,

s₁ , s₂ and s₃ are the sides of the triangle and

H is the height of the triangular prism.

Substituting the values, we get;

Thus, the surface area of the triangular prism is 252 ft²
