1. **State the problem:** We have a room with dimensions 30 ft long, 25 ft wide, and 14 ft high. There are 42 balloons inside the room, and we want to find how many cubic feet of space each balloon has. 2. **Formula used:** The total volume of the room is given by the formula for the volume of a rectangular prism: $$\text{Volume} = \text{length} \times \text{width} \times \text{height}$$ 3. **Calculate the total volume:** $$30 \times 25 \times 14 = 10500 \text{ cubic feet}$$ 4. **Calculate space per balloon:** Divide the total volume by the number of balloons: $$\frac{10500}{42} = 250 \text{ cubic feet per balloon}$$ 5. **Answer:** Each balloon has 250 cubic feet of space inside the room.
