Calculating Pool Volume

Jason is designing a rectangular swimming pool in his backyard. The length of the pool is 20 feet and the width is 12 feet. To calculate the amount of water needed to fill the pool, Jason needs to find the pool's volume. The volume of a rectangular pool can be calculated using the formula:

$$ V = L imes W imes H $$

where V is the volume, L is the length, W is the width, and H is the height of the pool. If the height of the pool is 4 feet, what is the volume of water required to fill it?
