The two methods in the lab for measuring the volume of a geometric solid object are weighing it on the balance and measuring it
Yakvenalex [24]

Answer:

Measuring with a ruler and using final volume minus initial volume

Explanation:

You can measure the volume of a geometric object by measuring its sides with a ruler and calculating the volume according to the corresponding formula for each object. For example, for a rectangular prism it would be

volume=length*width*height

You can also measure the volume of an object by measuring how much water it displaces. To do this you have to fill a measuring cylinder with enough water for the object to be completely submerged and take note of the volume. Then, add the object and note again the volume of the water+object. The difference between both is the volume of the object.

Volume of the object= volume of water and object - volume of water

The advantage of the second method is that it can be used for objects with irregular shapes as long as they do not float.
