Answer 2

Solution

• Length of glass =30 cm
• Bredth of glass = 25 cm
• Height of glass = 2 cm

Volume of glass=L×B×H

=30×25×2

=1500 ${cm}^{3}$

Mass=7.5 kg

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

$\frac{1500}{1000000} = 0.0015 \: {cm}^{3}$

$density = \frac{7.5}{0.0015} = 5 \times {10}^{3} \: kg /{m}^{3}$
