Volume of body = 180 cc
Explanation:
When a body is immersed in a water , its weight decreases due to upthrust of water . Thus decrease in weight = 550 - 370 = 180 G F
Thus the upthrust on body = 180 G F
Now this decrease in weight or upthrust is equal to the weight of water displaced by it .
Thus weight of water displaced is = 180 g
The density of water = 1 g/cc
Thus volume of water displaced = 180/1 = 180 cc
It is volume of body also
Therefore volume of body = 180 cc ( cubic centimeter )

Answer:
it may be 1.8cm3 as we need to convert 10m/s to 1000cm/s
