Remember that the femur is approximately one-forth of a person's height. Students should be able to use the following equations to fill in the missing measurements. (Round answers to the nearest unit). Students will begin by calculating the length of the femur given the height of the person, then they will use the reverse formula to find the height of a person given the length of the femur.
Mass of femur = (Total mass of person) / 5
Total mass of person = (Mass of femur) x 5
