Question

.................................................................

Hye,

The mass of an iron ball is 312 gram. The density of iron is 78 gram cubic centimetre . Find the volume of the ball.

Answer - 40 ( how it came??)

Answer 1

density=mass/volume
volume=mass/density=312g/78gcm'3
v=0.312kg/0.078kgcm'3=4cm'3

Answer 2

Hi sister !!!

density = mass / volume

{ as per density mass and Volume relationship }

note => we should look the same dimension while doing calculation .

according to your question

Mass of iron ball is 312 g

density => 78 cc

volume => Mass / density

volume => 312 g/ 72 cc

volume => 4 g/ cc

hope it helps you !!

thanks
