Verified Answer :

D = m / V

D = 31.7 / 35.3

D = 0.898 g/cm³

Answer: The density of block is \(0.90g/cm^3\)

Explanation:

To calculate mass of a substance, we use the equation:

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

We are given:

Volume of block = \(35.3cm^3\)

Mass of block = 31.7 g

Putting values in above equation, we get:

\(\text{Density of block}=\frac{31.7}{35.3cm^3}\\\\\text{Density of block}=0.90g/cm^3\)

Hence, the density of block is \(0.90g/cm^3\)
