Question

The dimensions of a block of glass are 25cm × 15cm × 4cm.find it's density if it's mass is 4.5 kg.no spamming​

Answer 1

Given:

Mass of Block,M= 4.5 Kg

Dimensions of Block= 25cm×15cm×4cm

To Find:

Density of block

Solution:

We know that,

• $\pink{\boxed{\bf{Density=\dfrac{Mass}{Volume}}}}$

$\rule{190}{1}$

Let the volume of block be V and density of block be D

So,

$\longrightarrow\rm{V=25\times15\times4}$

$\longrightarrow\rm{V=1500\ cm^{3}=0.0015\ m^{3}}$

Also,

$\longrightarrow\rm{D=\dfrac{M}{V}}$

$\longrightarrow\rm{D=\dfrac{4.5}{0.0015}}$

$\longrightarrow\rm\green{D=3000\ kg/m^{3}}$

Hence, the density of block is 3000 kg/m³.

$\rule{190}{1}$

Additional Information

Density

Density is defined as the ratio of mass of substance to volume occupied by substance.

Mass

Mass is defined as the amount of matter present in the substance.
