Question

a steel ball has s volume of 1500cm^3. the density of the ball is 95g/cm^3 . work out the mass of the ball in kg

Answer 1

`m = pV`

mass =
`1500 * 0.095 = 142.5kg = 152500g`

Answer 2

`Given:\\V=1500cm^3\\\rho= 95(g)/(cm^3) \\\\Find:\\m=?\\\\Solution:\\\\\rho= (m)/(V) \;\;\;/\cdot V\\\\m=\rho V\\\\m=95(g)/(cm^3)\cdot 1500cm^3=142500g=142.5kg`
