it's from the outside of the box. if 1 cub. ft is recommended for one 12" sub, for two 12" the size should be double, correct?

im not cashis but....i forgot about the triangle first...so to find area...base X height X width.

12*15*32=5760

then find out the triangle:

5*15*32=2400/2=1200

add those two numbers... 5760+1200= 6960 cubic inches.

convert that to cubic feet by 1728 (12*12*12). which is 4.03 cf.

oppps my bad on my first number. :p

anyway...the box is too big either way.

ur formula looks weird
isn't this the formula for trapeoid, (top+base)heigh/2 and for volume in this case, we times the above number by 32?

so it's like (12+17)15/2 and then convert that to cub ft? i just don't know how to convert it
