"длина лыжи равна 1,8 метров,а её ширина 10 сантиметров.какое давление оказывает на снег мальчик массой 54кг, стоящий на лыжах?массой лыж можно пренебречь \n"

I don't know the exact answer to your question, but I can guide you through the steps to calculate the pressure. To find the pressure exerted by the boy on the snow, you need to divide his weight by the area of contact between the skis and the snow. First, convert the length of the skis from meters to centimeters (1.8 m = 180 cm). The area of contact between the skis and the snow is the product of the length and width of the skis (180 cm x 10 cm = 1800 cm²). Then, divide the boy's weight by the area to find the pressure. In this case, it will be 54 kg divided by 1800 cm². I hope this helps!
