Question

Find the volume of a triangular prism with the following dimensions. Round to the nearest cubic unit. triangle base: 5 ft triangle height: 3 ft prism height: 7.5 ft 8 ft3 56 ft3 19 ft3 113 ft3

Answer 1

I don't know which number you meant for the prism height but this is what you do to find the volume of a prism: (area of the base)*(height of the prism)

So for this triangular prism, you do 1/2(5*3)(height of the prism)
Simplified to 7.5*height
