Question

A contractor is excavating a ramp into a trench for a construction project. How much dirt will the crew have to remove? To answer, find the volume of the triangular prism in the figure shown. Opening 4 x 6, ramp 8'deep

Answer 1

It’s hard to tell without a diagram. I’m assuming the height and base of the triangle are 4 and 6.

Area of triangular prism
1/2 * base * height * length
1/2 * 4 * 6 * 8
2 * 6 * 8
12 * 8
96 cubic feet or 96 ft^3
