To find the density of an object, you need to use the equation: D = M/V. This is density equals mass over volume.

Mass: 30 g
Volume: 10 cm3

30/10 = 3 

Density: 3 g/cm3

Answer: The density of the object is equal to \(3g/cm^3\)

Explanation:

Density of an object is defined as the ratio of its mass and volume. The chemical equation representing density of an object is:

\(\text{Density of an object}=\frac{\text{Mass of an object}}{\text{Volume of an object}}\)

We are given:

Mass of an object = 30 grams

Volume of an object = \(10cm^3\)

Putting values in above equation, we get:

\(\text{Density of an object}=\frac{30g}{10cm^3}=3g/cm^3\)

Hence, the density of the object is equal to \(3g/cm^3\)
