Question

A solid ball has a mass of 50 grams and a volume of 20 cm. What is the density?​

Answer 1

• Mass of solid ball, m = 50 grams

• Volume of solid ball, V = 20 cm³.

• Let the density be d.

Density = Mass / Volume

Density = Mass / Volumed = m/V

$d = \dfrac{50}{20} \\ \\ d = \dfrac{5}{2} \\ \\ d = 2.5 \: \dfrac{g}{ {cm}^{3} }$

The density of the solid ball is 2.5 g/cm³.

Answer 2

Answer:  density=mass/volume

=50/20=2.5

volume=density/mass

8900/3000=89/30=2.1

mass =density x volume

=5x4500

=22500
