Bags of dirt!!

[swiftskater1]

Okay, So we are going to be getting supplies to build a Savannah Monitor cage! for the substrate im using 50% Top soil/Dirt, And 50% playsand. (They like to burrow) The Tank is going to be 8 feet long by 4 feet wide. I need to make a two foot ground of the substrate. How many bags of 50 pound dirt/sand do you think i need? Im thinking 10 bags of soil, 10 bags of sand. Im not to sure though.




Thanks.
