AIM: Approximate weight of a cow
Requirements: cow, measuring tape
Procedure: 1. from the front leg bone to the last leg bone measure the distance
2. then measure the chest circumference with measuring tape
Info: formula for calculating cow weight = (chest circumference)^2 * length / 666
Note: the reading should be in inches
in our case chest width 72 inch and length was 52 inch so the approximate weight was 404 kg
