Find the mass of 1 m³ of the alloy if the ingot of this alloy, which has the shape of a rectangular parallelepiped with dimensions of 0.25 m, 8.5 cm and 1.2 dm, has a mass of 20.655 kg.
8.5 cm = 0.085 m; 12 dm = 0.12 m.
The mass of 1m³ alloy is
20.655 * 1: (0.085 * 0.12 * 0.25) = 20.655: 0.00255 = 8100 (kg).
Answer: 8100 kg.
