Question

A silver block of density 10.5g/cm3 and has a volume of 30cm3 find the mass

Answer 1

Given :

Density of block = 10.5 g/cm³

Volume of block = 30 cm³

What To Find:

Mass of block

Solution :

Density is defined as the ratio of mass of the object to the volume of the object.

We know , that

$\large\begin{gathered} {\underline{\boxed{ \rm {\red{Density \: = \: \frac{Mass}{Volume} }}}}}\end{gathered}$

Substuting the values

$\begin{cases}\large\bf{{\purple{ \longrightarrow}}} \rm \: \: 10.5 \: = \: \frac{Mass}{30} \\ \\ \large\bf{{\purple{ \longrightarrow}}} \rm \: \: Mass \: = \: 10.5 \: \times \: 30 \\ \\ \large\bf{{\purple{ \longrightarrow}}} \rm \: \: Mass \: = \:315 \: g \end{cases}$
