Let's see the given measurements on the rectangular prism.
The volume of a prism is found by multiplying the area of the base by the height of the prism.
V=Bh
In the case of a rectangular prism, the base is a square. The area of a square, and also the area of the base, is the side length s squared. We can use this to rewrite the formula.
V= Bh ⇒ V= s^2 h
We are given that h= 4 and s= 4, so we have enough information to calculate the value of V.
