An equilateral triangular plate with sides 10 m is submerged vertically in water so that the base is even with the surface. Expr
ess the hydrostatic force against one side of the plate as an integral and evaluate it. (Round your answer to the nearest whole number. Use 9.8 m/s2 for the acceleration due to gravity. Recall that the weight density of water is 1000 kg/m3.)
The writing is confusing, but as I understand it 21 is about 20% of 104 (21x100/104). The same prosentage of 500 equals 100,96 and I would round it to 101 (the answer of the first equasion x 500/100).
