Find the mass of 1m3 of the alloy, if the ingot of this alloy, having the shape of a straight parolelipiped

Find the mass of 1m3 of the alloy, if the ingot of this alloy, having the shape of a straight parolelipiped with a measurement of 0.25m 8.5 cm and 1.2 dm, has a mass of 20.655kg

Let’s translate measurements into cubic meters. 1) 8.5 cm = (8.5: 100) m = 0.085 m 2) 1.2 dm = (1.2: 10) m = 0.12 m The volume of a rectangular parallelepiped is “length * width * height”. If the volume of a parallelepiped is 0.00255 cubic meters, then it is 0.00255 part of 1 cubic meter. 3) V = 0.25 * 0.085 * 0.12 = 0.00255 (cubic meters) ingot volume The weight of the ingot is 20.655 kg, and the volume of the ingot is 0.00255 part of 1 cubic meter, which means that 1 cubic meter weighs 8100 kg. 4) 20.655: 0.00255 = 8100 (kg) weighs 1 cubic meter
