Mound dimensions

how high off the ground is the rubber?
how long is the slope from rubber to the end of the mound?

On a standard mound the rubber is supposed to be 10 inches off the ground. Themound is supposed to slope 1 inch down for every 10 inches along the slope, so I make out that it adds up to 100 inches to the cut of the grass?
I could be talking a load of crap mind you

Rubber is 10" above home plate. Slope is 1" of drop for each 12" of run. There is a flat area at the top of the mound surrounding the rubber. It extends 6" in front of the rubber. Therefore, the slope starts 6" in front of the rubber.
