The density of water is 62.4 lbs/ft^3. what mass of water in kg will a rectangular can hold if it measures 2.00 ft by 3.00 ft by 6.00 inches?
volume of can = 2.00ft x 3.00 ft x 0.500ft = ?ft^3.
mass = volume x density
Substitute volume from above and density of 62.4 lbs/ft^3 to obtain mass in pounds. Then convert pounds to grams and kg.
