Question

Find total surface area of triangular prism

Answer 1

200 cm²

Explanation:

The combined area of the two triangular faces is
`(15)(8)=120` cm².

The area of the back rectangular face is
`(8)(2)=16` cm².

The area of the bottom rectangular face is
`(15)(2)=30` cm².

The area of the slanted rectangular face is
`(17)(2)=34` cm².

Taking the sum of these areas, the surface area is
`120+16+30+34=200` cm².
