Could someone check my math?
I'm coming up with about 50 tons of #57 gravel to back fill my overdig. That seems like a lot...
I've got a True L that's 18x43x28 with a mostly 30" overdig. That would make the hole roughly, 23x48x33 which would be 152' of perimeter (I think).
So my trench is
Sound right?
Appreciate your help!!!

So my trench is
- 152'
- 30" wide
- 32" deep (I'm figuring 42" minus collar and decking)
- 1334 - sq ft of hole
- 954 - sq ft of pool
- =380 difference that needs back filled
Sound right?
