Question

The net of a triangular prism isgiven below. Find the surfacearea of the triangular prism.

Answer 1

Given:

Height of the prism = 9 cm

Dimensions of the base triangle are:

height of the triangle = 3 cm

Base length = 4 cm

Required:

Find the area of the triangular prism.

Step-by-step explanation:

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

`A=(Perimeter\text{ of the base}* length\text{ of the prism\rparen+\lparen2}* base\text{ area\rparen}`

Substitute the given values in the formula.

`A=[(4+4+4)*9]+2((1)/(2)*4*3)`
