I finally made the sub box today with different dimensions.
is my math right ?
what I did was measure as if it was two boxes then added them together
The lower box was 9”5/8 and top measurement was 5” so I did 95/8”+5” = 145/8” divided by 2 =7 5/16”
So it is 7 5/16”x9”x12 1/2” = 822.6563 cubic in for lower box
Upper box is
11” lower and 4 3/4” upper
11”+4 3/4” = 15 3/4” divided by 2 = 7 7/8”
So lower
7 7/8”x7 3/8”x12 1/2” = 725.9766
725.9766+ 822.6563= 1548.633 cubic inches
Right now my box is made at 20 1/2” wide so I’m going to have to cut it down by my calculations to 12 1/2” wide.
I just want to make sure before I cut it all my dimensions are inside of the box.
Thank you
After I get the right width I’m going to use construction adhesive on all seams inside of the box to make sure it’s sealed good I’ve already used wood glue and brad nails.
