How do you measure the volume of a solid? Can you use the same method to measure all solids? Why or why not.
To measure the volume of a rectangular solid, you can multiply length x height x width. To measure the volume of an irregular solid you have to use water displacement. Measure a certain amount of water in a graduated cylinder. Then, put the object in the water and record the new volume. Last, subtract the first amount from the second amount to find the volume of the irregular solid.
