A boy weighing 45 kg stands on skis. Each ski is 1.5 m long and 10 cm wide

A boy weighing 45 kg stands on skis. Each ski is 1.5 m long and 10 cm wide. How much pressure does the boy put on the snow? Compare this to the pressure a boy does without skis.

Solving this problem, one should not miss the moment that the boy is standing on two skis, therefore, the area must be multiplied by 2.
Given: m = 45 kg; a = 1.5 m; B = 10 cm = 0.1 m; g = 10 N / kg
Find: p
Decision:
P = F / S = (mg) / 2ab = (45 * 10) / (2 * 1.5 * 0.1) = 1500 Pa
Answer: p = 1500 Pa; about 10 times.
