just how thick are two short planks??

They can be of any thickness. Hardwood thicknesses are expressed in quarters rather than inches. For example 1" thick lumber is called 4/4, 1 1/2" is called 6/4 and 2" thick stock is 8/4.

just ask  what board size do u need but u don't want to look stupid so try 7.75by 31.75

square inches doesn't matter. 3/4" is thicker than 1/2"

Try the link below there are some information on wall thickness etc to DIN:-\n\nhttp://www.alzarfze.com/pages/pipemain.htm

at the very least seven inches.

Cut up little squares and stack them up until you get to a quarter inch or some measurable amount.  Then count the number of sheets and do some basic division to determine a single sheet thickness.

I think I can help you with this one... I learned how to do it in Kindergarten.\n\nPull your head out of your ass and measure.\n\nGood Luck!

perimeter = 2 (side1 + side2)\narea = side1 * side2

six inches\n\n\n\n\nLOL

1.27 mm - 1.55 mm (or .05 inches) for the thickness.

1650 lumber has a specific gravity of about 0.42.  This means its density should be close to 26.19 lbs/ cu. ft.  The one foot 2x4 should weigh 1.46 lbs.

First of all, a maximum deflection of L/720 (I think) is a bit of an "overkill" if you are designing a floor for residential use. I believe the code allows us to use a minimum of L/240 deflection for our floors joists. A stronger design deflection criteria of L/360 for our joists is more than sufficient to carry a live load of 40 pounds per square foot and a dead load of about 15 pounds per square foot.\n\nResidential codes require a minimum of 1-1/8" thickness for both the deck and subfloor. We normally use 1/2" decking under a 5/8" thk. sub-floor for joists spaced at 12" and 16"  o.c.\n\nI understand that spacing your floor joists (or your floor trusses...a truss is a structural system made up of horizontal, vertical and diagonal members joined together to act as a single member....are you really using trusses on your floor?) at 24" o.c. is more economical than spacing them at 12", 16" or 19.2" o.c. Assuming you are using 12" square tiles (granite), the spacing between the joists would only give you 2 tiles on that spacing. I don't think that you would need a subfloor thicker than 5/8" if you have a decking of 1/2" underneath. The sheathing's (plywood or OSB) main use is to distribute the loads unto the joists. I don't think two tiles will deflect that much in a spacing of 24" o.c. Besides, the deck and the subfloor are laid out in a certain pattern (which I assume you already know) that will make it stronger and thus have some fire rating qualities. \n\nThis means that you need not worry too much regarding the thickness of your sub-floor as long as you install the minimum thickness with the minimum decking thickness required. What you should worry about is if your joist (or your "trusses" as you term it) will be able to carry the load superimposed on it and be able to transfer these loads into the supporting walls (or beams, which is another question) and unto the foundation wall or footings below.\n\nMy suggestion, since your question is a bit unclear (what is the use of the floor, is it for residential or commercial, is it located on the first floor or on the upper floors, is it to be used as a cantilevered balcony or a supported deck,  is it to be used for the exterior or interior since exterior use may mean snow load, etc.)is for you to call the tile manufacturer and give you some answers giving them the description of how you plan to lay out your joists (trusses).\n\nI am an architect and one thing I always remember regarding structural questions....if I can't do it myself, let the manufacturer do it for you (be sure to put their answers in writing) or better yet, ask a structural engineer.

#6 vertical bars @ 12 in centers with 90 degree bends top and bottom, #8 lap bars horizontal full length and a total thickness of 12 inches. 3000 to 4000 psi concrete with crushed rock and a water cement ratio of under .45 should do the trick.

There are some right answers, but without delving into lots of equations, it is easiest to think backwards.\n\nHow many planks does he need for the last wall?  40 (20 from the manager, 20 left over from the 3rd wall).\n\nSo to finish the 3rd wall he needs the 40 plus the leftover 20, total of 60.  Again 30 from the manager, 30 leftover from the 2nd wall.\n\nTo finish the 2nd wall, he needs 40+30 or 70 planks.  Again this is 35 from the manager, 35 leftover from the 1st wall.\n\nInitially, he would need to start with 40+35 or 75 planks.  This is 37.5 from the manager and 37.5 from the stock.\n\nThe answer is that he needs 37.5 planks in his possession when he first goes to the manager.

most are 4 inches deep. guess someone would have to go diving to find out. it varies
