How much soil does this look like?

[Green Squall]

Can anyone help me estimate how much cubic feet of soil this is? I used one bale of promix (4 cu ft) and added a good amount of compost I get for free from the city. I'm thinking maybe 6 or 7 cubic feet? I'm trying to figure out what amount of amendments to add.

Shovel and rake are for scale and its about 7 inches deep.

I'd say 6 or 7 is a fair estimate.

0.668 cubic feet / 5 gallon bucket
