Ya the number 1s 320\nBut who in the world has a perfecr floor???\nPlus you dont know how the room is \nWhen doing a floor you want a reveal the same on all 4 side if you can to make it look right. \nYou would not want a tile 4inch on this end and 8 on the other.\nSo then is you do the math its\n320+16+20=356total\nthis will make sure that the floor looks correct and your not short\nI have been in the field 20yrs+ and trust me you never buy just what you need.\nIf you did that and you need 10 more pc and you went back the tiles would be from a differnt batch and not match up right.\nGoodluck

A square foot is an actual square measuring 12 inches in length on each of it's four sides.

multiply 14 by 15 = 210 sq ft.

You can do all these in google. For the first one, type in "4 square metres in square cm", and it tells you the exact answer. Do the same for the others. \nYou can then work out any others by yourself without needing to ask :)

If it's only the front, and assuming it's rectangular, it's 30 x 30 =900. If it is not rectangular, information is not sufficient to tell.

86.4in. x 5in. = 432sq.in. per shingle\n\n1.5kW = 1500 W\n1500W / 17W = 88.235 shingles\n\n432 sq.in. per shingle x 88.235 shingles = 38117.5 sq.in.\n\n38117.5 sq.in. @ 144 sq.in. per sq.ft. = 264.7 square feet

Check to see if you have 12-inch floor tiles.  If you do, you can use them as a guide.

6" is 0.5 feet. So, 14 x 12.5 = 175 square feet.

Assuming that they all finish and there are no ties for a given place, the answer is 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2

If all you care about is the floor space, you just need to multiply the length times the width.  135" is approximately 11 feet and 43" is around 4 feet.  So this will be approximately 44 sq. feet.\n\nIf you mean *cubic* feet of volume, then you multiply all dimensions.\nSo ~6 feet x ~11 feet x ~ 4 feet is 264 cubic feet.\n\nFor an exact answer:\nFloor area is:\n135 x 43 = 5805 sq. inches\n\nThere are 144 (12x12) sq. inches in a sq. foot.\nSo 5805 / 144 = 40.3125 sq. feet\n\nFor an exact volume:\n135 x 43 x 70 = 406350 cu. inches\n\nThere are 1728 (12x12x12) cu. inches in a cu. foot.\nSo 406350 / 1728 =  235.15625 cu. feet

You can find how many square feet the kitchen is by multiplying 18*15. This equals 270 sq. feet.  (The * means multiplication)\n\nSince each tile is one square foot, you will need 270 tiles.  Multiply the number of tiles by $18, and thats the cost to cover the floor.\n\nEquations:  \nLength * Width\n\n(Number of Tiles) * (cost per tile)

You mean, short of multipling it by itself? Well... we know that the squar of 500 is 250,000 and the square of 400 is 160,000. So the square of 482 will be somewhere in between, but closer to 250,000. I'd guess 230,000.

area: l*w = 256\n-> 4w*w = 256\n->w(sqaure) = 64\n->w=8 (width)\n->l = 4w = 4*8 = 32(length). \n\nThere you go.

12 x 16, that will equal square feet (192)\njust measure length times width to calculate square footage

43,560 square feet.  That's a square of about 209 feet on each side.
