Find the mass of an aluminum bar with a volume of 0.5 cubic meters. What is its weight?

We calculate the mass of an aluminum bar using the formula:
m = ρ * V, where m is the desired mass of the aluminum bar (kg), ρ is the density of aluminum (ρ = 2700 kg / m³), V is the volume of the aluminum bar (V = 0.5 m³).
Let’s calculate the mass of the aluminum bar:
m = ρ * V = 2700 * 0.5 = 1350 kg.
Aluminum bar weight:
Р = m * g, where g is the acceleration of gravity (we take g = 9.8 m / s²).
Let’s calculate the weight of the aluminum bar:
P = m * g = 1350 * 9.8 = 13230 N.
Answer: The mass of the bar is 1350 kg, the weight of the bar is 13230 N.
