# An indoor swimming pool is 105 feet long and 65.0 m wide. calculate the mass of water (density = .9998 g/ml) needed to fill the pool if it is 10.5 m deep. (1 ml = 1 cm^3). 11. a penny contains 97.0 % of zn and 3.00% of cu. calculate the density of a penny if the respective densities of cu and zn are 8.95 g/cm^3 and 7.14 g/cm^3. a hybrid car has a gasoline mileage of about 65.0 mi/gallon. how much money will it require to drive this car from irving to el paso if the distance between the two cities is about 755 mi and the gas costs \$ 5.99/gallon? barracudas are fast moving fish which can move at about 31.0 m/s in the open sea. express this speed in mi/h. how many significant figures are there in each of the following measurement?
