Four acrobats of mass 61.0 kg, 68.0 kg, 62.0 kg, and 55.0 kg form a human tower, with each acrobat standing on the shoulders of another acrobat. The 61.0-kg acrobat is at the bottom of the tower.

If the area of each of the 61.0-kg acrobat's shoes is 370 cm2, what average pressure (not including atmospheric pressure) does the column of acrobats exert on the floor?

I already found the normal force to be 2410.5, which is correct.
