Question

You built a skateboard ramp in the shape of a triangular prism. If you want to paint the entire ramp, even the bottom, what is the total area you will paint?

150 ft 2
210 ft 2
240 ft 2
180 ft 2

Answer 1

ar of ramp = ar of 2 rt triangles + ar of rect base + ar of rect. incline+ ar of the rect with dimensions5and4

ar 2 triangles = 2(1/2 x 5x12) = 60
ar of rect base = 12x4=48
ar of rect incline = 4x13=52
ar of rect with dimensions4and5 = 4x5 = 20
total ar = 20+52+48+60=180
