Question

The student lowers the iron block in a measuring cylinder. The liquid in the measuring cylinder rises from 50cm3 to 203cm3.
The iron block weight is 12N.
Calculate the volume of the iron block.

Answer 1

Answer:

As we know, Density d=

Volume,V

Mass,M

In this case, an iron block which has a volume of 12cm

3

= 0.12m

3

and a mass of 96g=0.096kg.

Therefore, Density d=

0.12

0.096

=8kg/m

3

.

Hence, the density of the iron block is 8 kg/m
