If the volume of a cylinder is 84,300 cubic centimeters then how many millimeters is this equal to
nevsk [136]

Answer:

84,300,000

Explanation:

Just multiply it by 1,000. 1cm = 10mm, and a cube is the length to a sort of third degree, so you take the 10 to its third degree as well and multiply it by 1,000, instead of 10 like you would to find how many millimeters were in an amount of centimeters. If that makes sense.

Andru [333]

Answer:
