Given :
Volume of packet = 350 cm3
Weight of the packet = 500 g
Density of water = 1 gcm-3
To find : Density of packet, in order to compare it with density of water and see whether the packet will float or sink
Density of packet = Weight of packetVolume of packet
= 500g350cm3
= 1.428 gcm-3
Therefore, the packet will sink because the density of the packet is greater than the density of water.
Question : It is easier for man to swim in seawater than river water because

Option 2: The density of seawater is more than the density of river water.
Option 3: The sea is deeper than the river.
Option 4: The sea is wider than the river.
