you can do a simple easy experiment to find the volume of a ping ball (water displacment). Place the ping pong ball in an amount of water with a known volume in a SI unit of volume (mL, liters). Notice the water has risen. Subtract the vslue of the original water from the new value of the water. This is the ping pong's volume.

Knowing the diameter of the ball allows you to calculate it. Using displacement of water allows to directly calculate it. Using direct measurement eliminates the error caused by the "dimples" on the ball's surface. (The minimum legal size for a ball has a volume of about 2.482 cubic inches or 40.68 cm3.)How to computeV = 4/3 (pi) r3 (4 x 3.1416 x radius cubed)How to measureThe easiest way to check would be to put a golf ball in a beaker of water. Fill a 200 ml beaker with water, and place the ball in it. Catch the overflow in another measured beaker. Since water is almost exactly 1 ml = 1 cc, the liquid displaced by the completely submerged ball will provide a close estimate of its volume in cm3.

The maximum volume for intradermal injection is 0.1 ml and the maximum volume for subcutaneous injection is 2ml.

You can't. There are an infinite number of different beakers, all with different areas and different lengths, that all hold 100 ml. The volume doesn't tell the dimensions.
