The total amount of concrete in the ramp ( $V_t$ ) will be the sum of the volume of the rectangular prism ( $V_{rp}$ ) and the volume of the triangular prism ( $V_{tp}$ )

$V_t=V_{rp}+V_{tp}$

The formulas are:

$V_{rp}=lwh$

Where "l" is the lenght, "w" is the width and "h" is the height.

$V_{tp}=\frac{bhl}{2}$

Where "l" is the lenght, "b" is the base and "h" is the height.

Substituting, we get:

$V_t=V_{rp}+V_{tp}\\\\V_t=lwh+\frac{bhl}{2}\\\\V_t=(18in)(6in)(6in)+\frac{(8in)(6in)(18in)}{2}\\\\V_t=1,080in^3$
