How much water does the cube displace?

[STLFAMILY]

A cube with edge 10 ft is submerged in a rectangular tank containing water. If the tank is 40 ft by 50 ft, how much does the level of water in the tank rise?

We have figured the volume of the cube to be 1000 cubic feet - that is as far as we have gotten - help please!
