Answer: [tex]V=360ft^3[/tex]
Step-by-step explanation:
The missing figure is attached.
You can calculate the volume of the concrete that will be needed to complete the ramp with the folllowing formula:
[tex]V=Bh[/tex]
Where "B" is the area of the base and "h" is the heigth.
The base is a triangle, then its area can be found with this formula:
[tex]B=\frac{ba}{2}[/tex]
Where "b" is the base and "a" is the heigth.
IN this case:
[tex]b=12ft\\a=10ft[/tex]
Then:
[tex]B=\frac{12ft*10ft}{2}\\\\B=60ft^2[/tex]
Since:
[tex]h=6ft[/tex]
You get that the volume is:
[tex]V=(60 ft^2)(6ft)\\\\V=360ft^3[/tex]
