The volume of the triangular prism: 59.2![ft^{3}](/tpl/images/0572/3724/60ebd.png)
The value of the concrete used is: 16*4 = $64
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo

As we know that, the formula to find out the volume of the triangular prism is:
V =
when h is the height and a&b are the length of the two square edges. So we have:
V =To find the concrete used in the ramp if the cost of concrete is $ 4.00 per cubic foot, we need to know the area of the ramp, which is:
S = 4*4 = 16![ft^{2}](/tpl/images/0572/3724/8b0c7.png)
Hence, the value of the concrete used is: 16*4 = $64
