Question

a 3.0m deep swimming pool measures 25m by 15m. it is filled with fresh water. what force does the water exert on the bottom of the pool?

Answer 1

equations i used were
Pressure = Pressure intial + density* gravity*height to find Pressure

then i used

Pressure= F/A
since A is the area i did (25 *16)

Answer 2

i mean 25*15

Answer 3

Seems all right. The force would be the weight of the water.

Answer 4

why?

Answer 5

Because water is at the top.
