A fishtank with inside dimensions of 50 cm X 25 cm X 30 cm is filled with water. What is the volume in cm3 of water required? What is the mass in grams of the water required? What is the mass in kilograms?
volume = length x width x height = ?cc.
mass H2O = volume x density. You don't have density listed; I assume the author of the problem wants you to assume the density of water as 1.00 g/mL.
