    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.
