Table Leg Area
1. **State the problem:** A table weighing 348 pounds is supported by 4 identical legs. Each leg exerts a pressure of 12 pounds per square inch on the floor. We need to find the area of the bottom of each leg touching the floor.
2. **Understand the relationship:** Pressure is defined as force divided by area, so
$$\text{Pressure} = \frac{\text{Force}}{\text{Area}}$$
3. **Calculate the force on each leg:** Since the table's weight is evenly distributed,
$$\text{Force per leg} = \frac{348}{4} = 87 \text{ pounds}$$
4. **Use the pressure formula to find the area:** Rearranging,
$$\text{Area} = \frac{\text{Force}}{\text{Pressure}} = \frac{87}{12}$$
5. **Calculate the area:**
$$\frac{87}{12} = 7.25 \text{ square inches}$$
**Final answer:** The area of the bottom of each leg touching the floor is $7.25$ square inches.
