A small statue of mass

Question

A small statue has a mass of 723.4g and displaces 68.6mL of water when added to a container of water.

 

a.) What is the density of the solid used to make the statue?

 

b.) You need to determine the density of a solid cube. Although you could determine the cube's density the same way the density of the statue was determined, describe an alternative method you could use?

Answer 1

a) density=mass/volume.

 

Density=723.4 g/68.6 mL or 10.5 g/mL.

 

b) Find the length of the side of the cube.  The volume is the length raised to the third power, length^3.
