1. The problem statement, all variables and given/known data Antartica is roughly semicircular, with a radius of 2000km. The average thickness of its ice cover is 300m. How many cubic centimeters of ice does Antartica contain? Assume we ignore the curvature of Earth. 2. Relevant equations (4/3 Pi r^3h)/2 3. The attempt at a solution I plugged r=2.0x10^8 and 3.0x10^5 and wound up with the answer 5.0 x 10^30 I jsut want to check if this is right. I jsut started my Physics course a couple days ago.
