How would you determine the density of an irregularly shaped object? a) It would be impossible to determine the mass of the object without more information. b) D = m/v, so measure the mass of the object using a balance. Then to find volume, measure the height, width, and length using an appropriate measuring tool. c) D = m/v, so measure the mass of the object using a balance. Then to find volume, fill a graduated cylinder with a known amount of water and immerse the object in the water. The amount of displaced water is the volume in cm3 or mL
