A brick has a mass of 100 G and a volume of 25CM3 what is the density of the brick

Explanation:

We are asked to find the density of a brick. Density is a substance's mass per unit volume. The formula for calculating density is as follows.

The mass of the brick is 100 grams and the volume is 25 cubic centimeters.

m= 100 g v= 25 cm³

Substitute the values into the formula.

Divide.

The density of the brick is 4 grams per cubic centimeter.
