Question

A block of glass 40 cm long, 35 cm wide and has a thickness of 2cm. Find its Density if its mass is 16.8 kg.

Answer 1

GIVEN :

$mass = 16.8 \: kg$

$volume = 40cm \times 35cm \times 2cm$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{40}{100}m \times \frac{35}{100}m \times \frac{2}{100}m$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =0.4m \times 0.35m \times 0.02m$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =0.0028 \: m^{3}$

TO FIND :

$density ={?}$

FORMULA :

$density = \frac{mass}{volume}$

SOLUTION :

$density = \frac{16.8 \: kg}{0.0028 \: {m}^{3} }$

$density = 6000 \: kg {m}^{3}$
