Find the mass of 1m3 of the alloy if the ingot of this alloy, having the shape of a rectangular parallelepiped

Find the mass of 1m3 of the alloy if the ingot of this alloy, having the shape of a rectangular parallelepiped with dimensions of 0.9 m, 2.5 dm and 8 cm, has a mass of 136.8 kg.

1. Determine the volume of the parallelepiped, while translating all its dimensions into meters:

0.9 mx 2.5 dm x 8 cm = 0.9 mx 0.25 mx 0.08 m = 0.018 m³;

2. Determine the mass of one cubic meter of this alloy. We take the unknown mass as a and make up the proportion:

0.018 m³ – 136.8 kg, 1 m³ – a kg;

0.018: 1 = 136.8: a;

a = (1 x 136.8): 0.018;

a = 7600 kg.

Answer: the mass of one cubic meter of this alloy will weigh 7600 kilograms.
