Yao Ming is 229cm in height and 140kg in weight. The average density of his wax figure is 0.9 times 10 times 3 kg / m3. The density of human body is about equal to that of water Please, what's the quality of Yao Ming's wax figure?
Yao Ming's volume: v = m person, ρ person = 140kg1.0 × 103kg / m3 = 0.14m3,
The mass of wax figure: m wax = ρ wax, v = 0.9 × 103kg / m3 × 0.14m3 = 126kg
A: the weight of Yao Ming's wax figure is about 126kg
