Determine the mass of a roll of aluminum foil with a thickness of 0.15mm. If you unwind the roll

Determine the mass of a roll of aluminum foil with a thickness of 0.15mm. If you unwind the roll, we get a tape measuring 0.2 × 15m.

Initial data: l (length of the aluminum tape) = 15 m; s (width of the aluminum strip) = 0.2 m; h (thickness of aluminum foil) = 0.15 mm = 0.15 * 10-3 m.

Reference values: ρ (density of aluminum) = 2700 kg / m3.

1) Determine the volume of a roll of aluminum foil: V = l * s * h = 15 * 0.2 * 0.15 * 10-3 = 0.45 * 10-3 m3.

2) Calculate the mass of the roll: m = ρ * V = 2700 * 0.45 * 10-3 = 1.215 kg.

Answer: The mass of a roll of aluminum foil is 1.215 kg.
