The lifting capacity of the elevator is 3 tons how many sheets of iron can be loaded

The lifting capacity of the elevator is 3 tons how many sheets of iron can be loaded into the elevator if each sheet is 3 m long, 60 cm wide and 4 mm thick

The volume of the sheet V is equal to the product of the length L and the width B and the thickness of the sheet d:
V = LBd = 3 m * 0.6 m * 0.004 m = 0.0072 m³.
Sheet weight m:
m = rV = 7800 kg / m³ * 0.0072 m³ = 56.16 kg (r – density).
Number of sheets n:
n = M / m = 3000 kg / 56.16 kg = 53.42 (M is the lifting capacity of the elevator).
Answer: 53 whole sheets can be loaded into the elevator.
