Question

A book of 100 meter Length 50 metre breadth and 12cm height has a mass of 20grams calculate it density​

Answer 1

Answer:

The Density is 3.3 * 10⁻⁸ g/cm³.

Explanation:

Dimensions of book,

Length = 100 m or, 10000 cm

Breadth = 50 m or, 5000 cm

Height = 12 cm

Volume = lbh

= [10000*5000*12] cm³

= 6 * 10⁸ cm³

Mass = 20 g

Density = Mass/Volume

= [20/6*10⁸] g/cm³

= 3.3 * 10⁻⁸ g/cm³

Hope this helps.
