70 POINTS PLEASE HELP! A dump truck pours sand into a container in the shape of a rectangular prism with a square base of length 2 feet. SEE PICTURE FOR REST

A

Step-by-step explanation:

The volume of a rectangular prism is:

Since the prism has a square base, each side length being 2, this means that both the length and width of our prism is 2. Therefore:

So, we can write:

The height h increases at a rate of about 8 inches or 8/12 = 2/3 feet per minute.

So, after t minutes, the height will be 2/3(t) feet. Thus, we can substitute:

We want to find after how long it will be until the volume is 64 cubic feet. So, V = 64:

Solve for t:

The correct answer is A.
