To find the area of the base of the right rectangular prism (box), we will use the formula for the volume of a rectangular prism, which is:
\[ V = \text{Base Area} \times \text{Height} \]
Given that the volume \( V \) is 50 cubic feet and the height \( h \) is 4 feet, we can rearrange the formula to solve for the base area \( A \):
\[ A = \frac{V}{h} \]
Substituting the given values:
\[ A = \frac{50 , \text{cubic feet}}{4 , \text{feet}} = 12.5 , \text{ft}^2 \]
Therefore, the area of the base is:
12.5 ft² (or 12.5 feet squared).
