**Problem:**

A brick of salt measuring 10.0 cm x 10.0 cm x 2.0 cm weighs 433 grams. What is its density?

**Solution:**

Density is the amount of mass per unit volume, or:

Density = mass/Volume

Step 1: Calculate Volume

Volume = length x width x thickness

Volume = 10.0 cm x 10.0 cm x 2.0 cm

Volume = 200.0 cm

^{3}

Step 2: Determine density

Density = mass/Volume

Density = 433 g/200.0 cm

^{3}

Density = 2.165 g/cm

^{3}

**Answer:**

The density of the salt brick is 2.165 g/cm
