Question

The mass of a block of metal (11:5+-0.5)kg and its volume is (1000+-20)cm3 how would you express the density of the metal?

Answer 1

`Density = 0.0112 (kg)/(cm^3)`
or
`Density = 1.12 * 10^-2 (kg)/(cm^3)`

Explanation:

`Density = (mass)/(volume)`

`Mass = 11.5 + (-0.5)`
`Mass = 11kg`

`Volume = 1000 + (-20)`
`Volume = 980 cm^3`

`Density = (11kg)/(980cm^3)`

`Density = 0.0112 (kg)/(cm^3)`
or
`Density = 1.12 * 10^-2 (kg)/(cm^3)`
