Q 4
Question

A stone sculpture weighs 225 g and has a volume of 90 cm³. Calculate its density and predict whether it will float or sink in water.

Show answer Hide answer
Answer
Density = 2.5 g/cm³; the sculpture sinks.

Explanation

Density
=
\( \dfrac{\text{Mass}}{\text{Volume}} = \dfrac{225\ \text{g}}{90\ \text{cm}^3} = 2.5\ \text{g/cm}^3 \)
  • Water has a density of about 1 g/cm³.
  • The stone's density (2.5) is greater than water's.
  • So the sculpture sinks in water.
Density is 2.5 g/cm³, greater than water, so the sculpture sinks.
