Volume in cm3: To find the volume in cm3, you will need to convert the dimensions of the tank into cm. The inside dimensions of the tank are 30.5 cm x 61 cm x 30.5 cm, so the total volume will be 90230.75 cm3. Mass in grams of water: The mass in grams of the water required to fill the fish tank can be calculated by multiplying the volume (90230.75 cm3) by the density of the water (1g/cm3). This would give a total mass of 90230.75 grams. Mass in kilograms: The mass in kilograms of the water can be calculated by converting the mass in grams (90230.75) to kilograms. To do this we can divide the mass in kilograms by 1000, giving us a total mass of 90.23075 kg. Weight in lbs of water: The weight in lbs of the water filling the tank can be calculated by multiplying the volume of the tank (1 ft x 2 ft x 1 ft) by the density of the water (62.4 lbs/ft3). This would give a total weight of 124.8 lbs.
