A container weighs 78.1 kg when it is filled with some cement. The same container weighs 25.5 kg when it is filled with some san d. The mass of the cement is 5 times as heavy as the mass of the sand. Find the mass of the container
1 answer:
Container + cement = 78.1
Container + sand = 25.5
Difference( cement - sand) = 78.1 -25.5 = 52.6
4 x Sand = 52.6
Sand = 52.6/4 = 13.15
Container = 25.5 - 13.15 = 12.35 kg
