20. You are putting in a pool at your house in the shape of a rectangular prism. The length is 40 ft . the width is 20 ft and the \( 3-\mathrm{D} \) height is 12 t . How much water will be in the pool?

To find out how much water the pool will hold, you can calculate the volume of the rectangular prism using the formula: Volume = Length × Width × Height. So, in this case, you multiply 40 ft (length) × 20 ft (width) × 12 ft (height). That gives you a total volume of 9,600 cubic feet! That's one big splash waiting to happen! When filling the pool, keep in mind that there could be some common miscalculations, especially with the height measurement. Make sure you're using the same unit throughout the calculation; if your height measurement is not in feet, convert it first! Remember to double-check your numbers to avoid over-filling (and flooding your backyard) or under-filling (and missing splash time). Happy swimming!
