if your ganna build a sealed box and it gonna be just a rectangle then take 3/4" off each outter dimension so if the total length of the box is 34 inches take 2 1/4" off the length 1 1/2'' for the 2 sides and 3/4 for the divide if its 20 inches tall then take off an 1 1/2'' and if its 14'' deep then tale off 1 1/2'' so you will multipy lxhxw

so it will be 31.75x18.5x12.5 this may not b exaclty how u build it but it gives u an idea after you multiply them all together then divide the total by 1728 cause theres 1728 sq inches in a sq foot then divide that by 2 and u wil have the cu ft that u need in each chamber the total sq ft in the box for these example measurements would be 4.24 sq ft and it would be 2.12 cu ft inside each chamber
