Question

If 160 L of molten metal is cast into 20 identical cubes, how many litres of paint will be required to paint all the cubes completely with a uniform thickness of 1 cm?

Answer 1

Answer:

volume of paint required for one cube = (TSA) * Thickness at each surface = 2400 * 1 = 2400cm³. Hence, → volume of paint required for 20 cubes = 2400 * 20 = 48000cm³.
