Calculate this, we use jackson -pollock seven -side technique.
00:09
So, according to the question, the body density equals to 1 .097 minus 0 .000 -4691, 1 multiply with sum of skinfold and then add 0 .000056 multiply with square of the sum of skinfold side and then subtract with 0 .0015.

1, 28, 28 and multiply with age.
01:02
So therefore body density equals to 1 .097 minus 0 .00046971 multiplied with 1675 plus 0 .000056 multiply with 165 plus 0 .0056 multiply with 2725 plus 0 .0056 multiply with 27 -225.
01:27
Minus 0 .00128 multiplied with 42.
01:37
So this is the first equation.
01:39
So here we get 1 .097 minus 0 .07 plus 0 .075 plus 0 .015 minus 0 .005.
01:54
After solving them, we get 1 .03.
02:01
So the body fat percentage equals to 495 upon body density minus 450.
02:14
So here we get 495 upon 1 .03 minus 450 so 580...
