![### How to Calculate the Area of the Base of a 3-Foot Tall Chest with a Volume of 75 Cubic Feet
**Problem Statement**:
You are building a 3-foot tall chest. You want the volume to be 75 cubic feet. What should the area of the base be?
**Volume Formula**:
The volume \( V \) of a rectangular prism (or chest) is given by:
\[ V = \text{area of the base} \times \text{height} \]
**Given Data**:
- Height of the chest \( h = 3 \) feet
- Volume \( V = 75 \) cubic feet
**Step-by-Step Solution**:
1. **Write down the volume formula**:
\[ V = A \times h \]
where \( A \) is the area of the base.
2. **Substitute the known values into the equation**:
\[ 75 = A \times 3 \]
3. **Solve for the area of the base \( A \)**:
\[ A = \frac{75}{3} \]
\[ A = 25 \]
Therefore, **the area of the base should be** \( 25 \) square feet.
**Explanation of Diagram**:
The diagram shows a rectangular prism representing the chest. It indicates the height is 3 feet and the volume is 75 cubic feet. To find the area of the base, one would use the given formula and values as shown in the solution above.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F98c10d56-5808-42e0-91f9-a6dff3f2284b%2F4cc5fb56-4b51-4dff-857d-605a910de683%2F4ciuz3_processed.jpeg&w=3840&q=75)
