Find the hydrostatic pressure on the bottom of the aquarium in lb/ft^2

[jorgegalvan93]

Homework Statement

An aquarium 5 ft long, 1 ft wide, and 5 ft deep is full of water. (Recall that the weight density of water is 62.5 lb/ft3.)

(a)Find the hydrostatic pressure on the bottom of the aquarium in lb/ft^2

Homework Equations

hydrostatic pressure = ρgd = δd
ρ = 62.5 lb/ft^3
g = 9.8 m/s^2
d = 5ft

The Attempt at a Solution

The equation is straightforward, but obtaining my answer in the unit asked, that's the problem. How does eliminate s^2?

It says "weight density", and it asks for the answer in units of lb/ft^2, so I would assume all references to lbs here mean "lbs weight", not lbs mass. That means you don't need to multiply by g - it's included in the units.
