Question

7 m The side lengths of the base of a triangular prism are 7 meters, 5 meters, and 8 meters. The height of the prism is 12.5 meters. 12.5 m 6 m What is the lateral surface area of the prism in square meters? 5 m

Answer 1

Given a triangular prism with side lengths of the base as a, b, and c, and height h, then the lateral surface area, A is given by

`A=(a+b+c)h`

In our case,

`a=5m,b=6m,c=7m,\text{ and }h=12.5m`

Hence,

`A=(5+6+7)12.5=18*12.5=225m^2`

Therefore, the lateral surface area in square meters is 225
