### 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.
