Fortunately, farming is science, and science comes to our rescue once again. Some ingenious farmer at some point recognized a mathematical correlation between the size and weight of a pig. Apparently you can estimate with some accuracy the weight of pigs over 150 pounds by squaring their girth behind the shoulders, then multiplying by length from back of head to tail and dividing that product by 400.
(girth x girth x length) / 400 = weight in pounds
By this formula, a pig that is 40 inches in girth and 45 inches long would weigh about 180 pounds:
(40 x 40 x 45) / 400 = 180
If the pig is less than 150 pounds, you adjust the formula by adding 6 to your result.
(girth x girth x length) / 400 + 6 = weight in pounds
So, a slightly smaller pig, 35 inches in girth and 32 inches long would be 104 pounds:
(35 x 35 x 32) / 400 + 6 = 104
So there you go: your math and science lesson of the day. I hope I got the parentheses in the right places.
