First of all, to find how much water can the tub hold like finding the volume of the tube, and the tube is a rectangular prism, so we have the volume of it equal length × width × height. So we just need to put the information in here which V= 5×3 1/2×4 1/4=74.375 cubic feet. As a result, the tube could hold 74.375 cubic feet water.
If you multiply 15 by 2 you were to get 30 but since it is 15 multiplied by 20 instead its like adding a 0 at the end of the number so we change 30 to 300.
