Question

you have 3600 sq ft of 12x12 tile. the tile is packaged 12sq ft per box. the tile is shipped on a pallet witch holds 72 boxes of tile. how many boxes will u need to fill the order? how many full pallets will there be?

Answer 1

Every 12x12 tile is a square foot (assuming "12x12" is in units of inches of course).

So, we need 3600 tiles (assuming the problem is to cover 3600 sq ft of space)

How many boxes at 12 tiles per box?... 3600/12 = 300 boxes

How many pallets does this consist of?  300 boxes divided by 72 (boxesperPallet) = 4.167 pallets 

So that's 4 full pallets.

 

Remember, keep good track of units (don't make any assumptions you can't take back to the store ;-)

 

Extra Info:  Notice how the units come through the division in step 3:  3600 sqft / 12 sqft per box....

    sqft

sqft/box

 

a "double-divide" appearing in a fraction as above brings box to the numerator.... =300 boxes
