How can you measure the volume of an irregular object which is insoluble in water

first of all check how much ml of water is there for eg: if its 100ml add your object after adding the object check how many ml are there for eg:150 ml after adding the irregular object so the volume of the irregular is 50

Explanation:

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
