Question

An object has a length of 5.0 cm, a height of 3.0 cm and a width of 15.0 cm. It has a mass of 24 grams. What is its density?
9.4
0.11
2.25

Answer 1

Volume of the object 
5 * 3 * 15
225 cm^3

Mass of the object 
24 grams

Density of the object
Mass / Volume
24 grams / 225 cm^3
0.107 g/cm^3

Answer 2

Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance.

Density = 24 g / (5 x 3 x 15) cm³

Density =0.11 g/cm³
