Given that 1 cubic cm of marble weights 0.25 kg, the weight of marble block 28cm in width and 5cm thick is 112kg. Find the length of block.
Weight of 1cm3 = 25 g
Total weight in gms = 112 * 1000 = 112000 g
Volume = 112000/25 = 4480 cm3
Volume = Length * Width * Height
Length * 28 * 5 = 4480
Length = 32cm
