Answer:
volume of the rubber ball above the surface of water=
7
2
therefore, volume of the rubber ball below the surface of water1−
7
2
=
7
5
So, average relative density of the rubber ball=
volumeoftheball
Volumeofthebelowthesurfaceofwater
7×1 =5
=0.71
We get, Average density of rubber ball is 0.71.

Answer:
The volume of the rubber ball above the surface of water = 2/7
The volume of the rubber ball below the surface of water = 1 - 2/7 = 5/7
so, the average relative density of the rubber ball = 5/7 = 0.71.
∴ The average density of rubber ball is 0.7
