Question

a swimming pool is 50m long and 20m wide. its shallow and deep ends are 1.5m and 4.5m deep.if the bottom of the pool slopes uniformly find the amount of water to fill the pool?

Answer 1

volume of water = area of cross section * length
                          = {1/2 * 20*(1.5+4.5)} * 50
                          = 60*50
                          =3000 cubic m Ans
