Answer:
0.204 KN
Step-by-step explanation:
Height above cube h= (100-15)/100 = 0.85 m
a) force on the top of the cube = ρgh×area
= 1000×9.81×0.85 = 8330 N/m^2
= 833 KN/m^2*0.15^2= 0.187 KN
b) Force on one side of the cube
on top = 8.33 KN/m^2
at bottom ρgh
= 1000×9.8×100/100
=9800 N/m^2
Net Force = area of the diagram
= 8.33×(15/100)^2 + 1/2(9.8-8.33)×(15/100)^2
= 0.204 KN
