Answer:
8.7 ft
Step-by-step explanation:
The diagram of the ramp is attached below.
Volume of a Triangular Prism = Base Area X Width
From the diagram:
Base of the triangle = 6 ft
Height of the Triangle = 12 ft
Therefore:
Base Area of the Prism [tex]=\frac{1}{2}X 12X6=36$ ft^2[/tex]
From the diagram, Width of the ramp =x
Given that the volume of the ramp is 313.2 cubic feet.
Therefore, substituting into the formula for Volume of a Triangular Prism
[tex]313.2=36 X x\\x= 313.2 \div 36\\$Width of the ramp, x=8.7 ft[/tex]
