A homework problem states:
An aquarium 5 ft long, 2ft wide, and 3ft deep is full of water. Part C: find the hydrostatic force on one end of the aquarium.
Questions (I've completed part a and b. B asked for the force on the bottom which was 1875 lbs.:
What exactly does one end of the aquarium mean?
Is there a standard to applying long and wide in mathematics problems? It may not matter in calculating area, but in other instances it might. For example, calculating the area of a vertical standing slice would either have to be 2dx or 5dx.
My solutions manual shows that part C requires setting up an integral with a range from 0 to 3. This means that the "one end" of the aquarium is the top side? How else could the range be 0 to 3?
Here's my drawing of the aquarium:
