**I don't remember how i did this: "Find fluid force on vertical side of tank where..."**

Find the fluid force on the vertical side of the tank, where the dimensions are given in feet. Assume that the tank is full of water. (The weight-density of water is 62.4 pounds per cubic foot.)

So F = (w) int_a^b (hL) dy

w=62.4

a=0

b=8

h = 8-y (the depth)

L = 3/2 (the length between the left and right lines)

I'm reviewing my homework and I don't know how I got L = 3/2 I must have just guessed the slope or something. How would a constant be the length when the distance between the lines is changing?
