3. Use the measured dimensions of the 250 g mass to calculate the volume of the mass based on its shape (either hexagonal or cylindrical). State the shape of your mass, e.g., circular cylinder or hexagonal cylinder. Show your work. (Hint: If you do not know the formula for the volume of your shape, look it up on the internet.) 4. Determine the percent difference between the measured volume of the 250 g mass and the value calculated from the buoyant force measurement. Show your work. 5. Using the fact that 1 mL = 1 x \"IO\"8 m3, compare the volume of the displaced water to the calculated volume of the mass from Post-Lab Question 3 with a percent error calculation. Show your work.
