Question

A cube of metal weighs 1.45 kg and displaces 542 mL of water when immersed. Calculate the density of the metal.

Answer 1

Answer:

The Density of the cube of metal is 2.675g/mL or 2675kg/mL.

Explanation:

Given the following data;

Mass of metal = 1.45kg to gram (g) = 1.45 × 1000 = 1450g

Volume of the cube of metal = 542mL

Density = ?

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the equation;

$Density = \frac{mass}{volume}$

Substituting into the equation, we have;

$Density = \frac{1450}{542}$

Density = 2.675g/mL

In kilograms, the density is 2.675 x 1000 = 2675kg/mL.
