I need to fill my swimming pool for the summer. I will need to call the local pool supply store to schedule a water delivery truck. The company requires me to tell them the shape and the dimensions of the pool when I call. Why would they need to know the shape and the dimensions?

My pool is a rectangular shaped pool. It has a width of 10 feet and a length of 18 ft. the whole pool as a depth of 5.5 ft.

The delivery trucks can carry 3,000 gallons of water. They charge $0.04 per gallon and an extra delivery fee of $15 per truckload.

How much water is needed to fill the pool? (1 ft3 = 7.48 gallons)

How much water can one delivery truck carry?

How many trucks are needed?

How much will the delivery cost be?
