Question

What is the surface area of the triangular prism?

Answer 1

The surface area of the triangular prism is 135 feet squared

How to find the surface area of a triangular prism?

The surface area of a triangular prism is the sum of the area of the whole faces.

Therefore, it has 3 rectangular faces and two triangular faces

area of triangle = 1 / 2 bh

where

• b = base
• h = height

Therefore,

area of the triangle = 1 / 2 × 2.5 × 6 = 7.5 ft²

area of rectangle = lw

where

• l = length
• w = width

Therefore,

area of rectangle 1 = 8 × 2.5 = 20 ft²

area of rectangle 2 = 8 × 6 = 48 ft²

area of rectangle 3 = 8 × 6.5 = 52 ft²

Therefore,

surface area = 7.5 + 7.5 + 20 + 48 + 52 = 135 ft²
