You will need to have the formula ready to use. You can then input the numbers and find out the information.
I believe its 300 lbs. click the below link... http://www.staples.com/sbd/reviews/product-reviews/Office-Supplies/Storage-Desk-Organizers/Corrugated-Box-Storage/Lift-Off-Lid-Storage/Bankers-Box-Hang-n-Store-Storage-Boxes/Bankers-Box/p/908640-Bankers-Box-Hang-n-Store-Storage-Boxes-2-Pack.html
Use some standard of cardboard wt. per square ft, as a box has six sides, you have (length x width + length x height + width x height) x 2 x lb/ sq ft or if in metric kg/ sq m. Get net weight by subtracting cardboard wt from box wt. One standard cardboard box wt. in US is 0.13 kg/ sq m. This number will vary in US and, may be quite different in other countries.

=(Bursting Strength*1000)/GSM
(Bursting Factor X Gram per Square Meter)
Bursting factor times grams per square meeting is the formula for calculating bursting strength of a cardboard box. It shows the pressure required due to weight to cause the breach. The bursting strength is printed on the bottom of the carton.

Corrugated Board - Ring Crush Test : Ring Crush is a traditional test of linerboard and corrugating medium strength. Ring crush measures compression resistance, and this compression strength is considered to relate to the eventual compression strength of combined board made from the component. Linerboard called high strength or high performance linerboard is board that is able to achieve a specified minimum ring crush at basis weights that are lower than traditional basis weights. Corrugated Board - Concora Crush Test : The Concora Crush Tester performs a series of tests to determine the rigidity and crush resistance of corrugated material. It is used in conjunction with the Concora Liner Tester. The first test measures the flat crushing resistance of a laboratory-fluted corrugated material. The second test determines the edgewise strength, parallel to the flutes, of a short column of single-, double-, or triple-wall corrugated board. The third test evaluates the ability of corrugated material to contribute to the compression strength of a corrugated box by measuring the edgewise compression strength of a laboratory-fluted strip of corrugated material in a direction parallel to the fluted tips. Corrugated Board - Flat Crush Strength : The flat crush test is a measure of the resistance of the flutes in corrugated board to a crushing force applied to the surface of the board under prescribed conditions. Flat crush is a measure of the flute rigidity of corrugated board. A high flat crush value indicates a combination of good flute formation and at least adequate strength medium. Low flat crush may indicate a number of conditions including low strength medium, leaning flutes and crushed flutes.From: http://www.thaicorrugated.com/knowledge.php?cid=30
The blank size is the length and width of a flat corrugated box before it has been formed into a finished box.
Corrugated boxCorrugated box is box made out of corrugated box made of paper based corrugated fiberboard. Corrugated fiberboard is a paper-based material consisting of a fluted corrugated sheet and one or two flat linerboards. It is widely used in the manufacture of corrugated boxes and shipping containers. Corrugated liner marked with parallel folds, ridges or furrows bent into regular curved folds or grooves. Process of making such regular curved folds is called corrugation.
