The question wants us to find 3 times the volume of the pool. This is because we are told that the pool must be filled 3 times during the summer and asked how many cubic feet of water is required to fill the pool all summer.
Step 1: Find the volume of the pool. Volume is calculated by multiplying length by width by height. Pool length = 5 ft. Pool width = 4 ft. Pool height = 2 ft. Pool volume = 5 • 4 • 2 5 • 4 • 2 = 40 The volume of the pool is 40 cubic feet.
Step 2: Find 3 times the volume of the pool. Volume = 40 ft.^3 3 times volume = 3 • 40 ft.^3 3 • 40 ft.^3 = 120 ft.^3 3 times the volume of the pool is 120 cubic feet.
Answer: The pool requires 120 cubic feet of water in order to be filled enough over the course of the summer.
We know that the volume of a cone is given by the following relation: V = (pi * r^2 * h)/3 where r is radius and h is height of the cone In our case, radius is diameter divide by 2: V = (pi * (8/2)^2 * 10) / 3 = 167.55 cubic inches So the container holds 167.55 cubic inches
