Answer:
200 square centimeters or 20000 square millimeters
Step-by-step explanation:
The formula for the volume of a cone is V = Bh where B is the area of the base and h is the height. So, in your problem, 200 cubic cm = 200000 cubic mm.
Therefore 200000 = 10B
B = 20000 square millimeters or 200 square centimeters
