The total amount of concrete in the ramp () will be the sum of the volume of the rectangular prism () and the volume of the triangular prism ()
The formulas are:
Where "l" is the lenght, "w" is the width and "h" is the height.
Where "l" is the lenght, "b" is the base and "h" is the height.
Substituting, we get:
