The volume of a prism V can be calculated using the following formula.
V=Bh
In this formula, B is the area of the base and h the height of the prism. First, we can calculate B. The base is a rectangle. Therefore, to find its area, we will multiply the rectangle's length l by its width w.
B=l w
By substituting 6 for l and 14 for w, we can find B.
We found that the area of the base B is 84ft^2. We are also given that the height h equals 5ft. Let's substitute these values into the formula and find V.
