Question

A rectangular block of copper metal weight 64g the dimensions of the block are 8 cm 4 cm and 6 cm calculate the density of the block​

Answer 1

Answer:

Given:

Weight of the block = 1896 g

Length of the copper box= 8.4 cm.

Breath of the copper box = 5.5 cm.

Height of the copper box= 4.6 cm.

To find: Density of copper

Solution:

volume of the copper box = l×b×h

=

= 212.52 cubic cm.

Density of copper = weight / volume

So, density of copper =

= 8.92 gm/cc.

So, the density of copper is 8.92 gm/cc.
