1. **Problem Statement:** Calculate the volume of a warehouse shaped as a rectangular prism with dimensions length = 31 ft, width = 25 ft, and height = 30 ft. 2. **Formula:** The volume $V$ of a rectangular prism is given by the formula: $$V = \text{length} \times \text{width} \times \text{height}$$ 3. **Substitute the given values:** $$V = 31 \times 25 \times 30$$ 4. **Calculate step-by-step:** - First multiply length and width: $$31 \times 25 = 775$$ - Then multiply the result by height: $$775 \times 30 = 23250$$ 5. **Interpretation:** The volume of the warehouse is $23250$ cubic feet. This means the warehouse can hold $23250$ cubic feet of space inside it.
