PBW for height 180 cm using PBW = 50 + 0.91 × (height_cm − 152.4) for men is approximately?

Estimating PBW from height uses a simple linear equation that anchors at a reference height and adds a proportional amount for every centimeter above that height. For a height of 180 cm, subtract the reference height 152.4 cm: 180 − 152.4 = 27.6 cm. Multiply by 0.91: 27.6 × 0.91 ≈ 25.116. Add the base 50 kg: 50 + 25.116 ≈ 75.116 kg. Rounding gives about 75.1 kg. So the predicted body weight is approximately 75.1 kg, which matches the given option.
