An aquarium shaped like an inverted cone has a height of $8$ $\text{m}$ and a base radius of $2$ $\text{m}$. If the aquarium is full of water, how much work is required to pump all the water to the top of the aquarium and out? (Use $1000{\text{kg/m}}^3$ for water density and $g=9.8{\text{m/s}}^2$).
