Cubic inches for 8ga.

[Homeownerinburb]

I am looking at a project where I will be joining 8-3 nm to thwn in conduit. In calculating the size box necessary, how many cubic inches does each piece of 8ga need? And the ground will be 10ga, how many cubic inches for 10ga?

Thanks.

So I'll need a minimum of 21 cubic inches.
