Answer 2

Answer:

The statements that are true about the ramp is:

• The shape can be broken into a rectangular prism and a triangular prism.

Step-by-step explanation:

Clearly from the figure given to us we observe that:

1. It is made up of a rectangular prism and a right angled triangular prism.

• Also, if B is the base area of the rectangular prism (i.e. square base) and h is it's height then the volume of the Rectangular prism is:

$Volume=Bh$

Also, for the triangular prism the base area is halved and hence the base area of triangular prism is: B/2

Hence, the total volume of Triangular prism is: $\dfrac{1}{2}Bh$

Hence, the total volume of figure is:

$Bh+\dfrac{Bh}{2}$

• Also, we have Base area B=4 square ft. (Since, it is made up of square base with side 2 ft. )

                        and h=4.8 ft.

                       Hence, volume of figure is:

$4\times 4.8+\dfrac{4\times 4.8}{2}\\\\\\28.8 cubic ft.$
