Question

The density of copper is 9.86 g/cm^3 and its volume is 150cm^3

work out the mass of the solid copper cubiod in kg.

Answer 1

Density=mass/volume, 9.86=mass/150, so mass=150×9.86=1479g=1.479kg.

Answer 2

The mass of the solid copper cuboid is 1.479 kg.

Explanation:

Given density and volume of copper we have to find the mass of the solid copper cuboid in kg.

`\text{The density of copper=}9.86(g)/(cm^3)`

`\text{Volume=}150 cm^3`

As,
`Density=(Mass)/(Volume)`

⇒
`\text{mass of solid copper=}Density* Volume=9.86* 150=1479g`

⇒
`mass=1479g=(1479)/(1000)kg=1.479 kg`

Hence, the mass of the solid copper cuboid is 1.479 kg.
