To calculate the volume of a rectangular prism, you need to know the length, width, and height of the prism. The formula for finding the volume of a rectangular prism is:Volume = length × width × heightFor example, if the length of the prism is 5 units, the width is 3 units, and the height is 10 units, you can calculate the volume as follows:Volume = 5 units × 3 units × 10 unitsVolume = 150 cubic unitsTherefore, the volume of the rectangular prism is 150 cubic units.
