Question

Find the surface area of a triangular prism with the dimensions of 14 16 and 18

Answer 1

To find the height of the triangle we can use pythagorean theorem or a squared to b squared = c squared with c as the hypotenuse.

14 squared + height squared = 16 squared
196 + height squared = 256
height squared = 60
height = 2
`√(15)`

The formula for surface area or total area is:
perimeter x height + 2 x area of base
30 + 2
`√(15)` + 28
`√(15)`
30 + 30
`√(15)` = final answer
