Question

8. A rectangular metal block measuring 10 cm x
5.0 cm x 2.0 cm. Its mass is 250 g. What is the
density of the metal?

Answer 1

Answer:

Length, breadth and height of rectangular block are 10 cm,5 cm and 2 cm respectively.

Volume of block, V = l×b×h

or, V = 10×5×2 = 100 cm^3

Mass of block, m = 250 g

Density of block ,D = m/V

or, D = 250/100 = 2.5 g/cm^3

Hence, Density of block is 2.5 g/cm^3...
