Q

Calculate the weight in kilograms (kg) of three pieces of steel plate that are 42 mm x 1.4 m x 4 m (h x w x l) in size.

A

Answer:

Convert measurements to meters: h = 42 mm ÷ 1000 = 0.042 m.

Calculate the volume: Volume = (0.042 m x 1.4 m x 4 m) x 3 = 0.2352 m³ x 3 = 0.7056 m³.

Calculate the mass: Mass = 0.7056 m³ x 7,850 kg/m³ = 5,539 kg.

Explanation: This calculation involves converting measurements, calculating the volume of the plates, and then determining the mass based on the density of steel.
