A ramp is being constructed with wood and then filled with concrete. How many cubic get of concrete will be needed to complete the ramp?

The cubic volume of concrete needed to complete the ramp is 360 ft³

Step-by-step explanation:

We note that the ramp shape is that of a right ngled triangular cube with dimensions

Height = 10 ft

Base = 12 ft

Width = 6 ft

The amount of concrete to fill the ramp is approximately the volume of the ramp.

Volume of ramp = volume of triangular prism = 0.5×Base ×Height  × Width

Volume of ramp = 0.5×12×10×6 = 360 ft³.

The cubic volume of concrete needed to complete the ramp = 360 ft³.

this is answer of 144 cubic meters
