How to solve for volume of a regularly shaped object 1. 2. 3. 4. 5. 6. Volume = length x width x height. You only need to know one side to figure out the volume of a cube. The units of measure for volume are cubic units. Volume is in three-dimensions. You can multiply the sides in any order. Which side you call length, width, or height doesn't matter. How to solve for the volume of an irregular shaped object 1.Add water to a graduated cylinder of beaker an record the original amount as “a” 2Place the object in the graduated cylinder, and record the resulting water volume as "b." 3.Subtract the volume of the water alone from the volume of the water plus the object. For instance, if "b" was 50 milliliters and "a" was 25 milliliters, 50-25= 4. This number is the volume of the irregularly shaped object would be 25 milliliters. Original volume = Original volume = -Volume w/ object= -Volume w/ object= Volume of object= Volume of object=
