What is the distance from 1st base to 3rd with 80 foot bases?

You can find the distance between first and third on any Baseball or softball field by using the following formula:

A squared plus B squared equals C squared.

A is the distance between home and first base

B is the distance between home and third base

C is the distance between first base and third base.

So with 70 ft. bases, it would be 99 feet.
