How many 11x11 floor squares package of 10 are needed for 9x20 dance floor?

Assuming that the floor squares are 11" x 11" and the dance floor is 9ft x 20ft, we can proceed as follows. 9ft = 108 inches and 20 ft = 240 inches. The product of the two which is the ares of the dance floor is 25920 square inches. Divide this by (11 x 11 = 121) to get 25920/121 = 214.214 squares. Since each package has 10 squares you would need 21.4214 packages. Since the shop keeper will not sell you fraction of a package plan on getting 22 packages.


How many 18 inch by 18 inch tiles do you need to cover 121 square feet?

53.77 is the text book answer, but you will need at least 10 to 20 more tiles depending on the layout of the floor. A good layout is a balanced layout that starts at the center of the main entrance. There will be corners and side cuts. Cuts around doors, vanities, kitchen islands, closets, etc. There is also the damage and waste factors. Tiles do break!I have laid many floor tiles and I found it best to set up a floor plan drawing of the floor and account for all of the cuts before I start then add in 20% more for waste. It happens.
