When you are getting the "total cu. area"
of the out side dimensions of a box size
what do you do if the width is 2 different
sizes.? like 14"w at top & 12"w at bott.
do ya add them & then average them.? like you
would if you had 2 different depths.?
14" x 12" x 9.50" x 6" using 3/4"
tw bw h d
thats the weasurements,i've never had 2 diff.
width meas. so I'm just lost . and really do appreciate any of the help..

Didnt you take math class?

so you have a box with the shape something like this


   ____________________
  /                    \
 /                      \
/________________________\

Something like that. All you have to do is split the box up into 3 sections like so


   ____________________
  /|                  |\
 / |    2             | \
/_1|__________________|3_\

V= B1+B2+B3
=(B*H/2 + L*W + B*H/2)*Depth

Get all that?

9.50x(26/2)x6
=9.5x13x6

1/2height(top width+bottom width)=arearemember to subtract width of material from figures. all figures are in inches.to find volume:area x length= volumeto convert to cu. ft., since it's in cu. inches:vol. divided by 12 3 times
hope this helped, it sure helped me, i must have done these operations a million times trying to squeeze the most cu. ft. i could out of a small area.------------------

if the top and bottom run parallel, and the front is slanted, it's a trapezoid. the formula for a trapezoid's area is:

1/2height(top width+bottom width)=area

remember to subtract width of material from figures. all figures are in inches.

to find volume:

area x length= volume

to convert to cu. ft., since it's in cu. inches:

vol. divided by 12 3 times

hope this helped, it sure helped me, i must have done these operations a million times trying to squeeze the most cu. ft. i could out of a small area.

Multiply the top, bottom, and side. Then divide by 12 3 times. There you go.

------------------
1 10 going for 145+
2 10's going for 150+
Wish me luck

Or instead of dividing by 12 3 times you could just divide by 1728.
