12 feet X 13 feet = 156 square feet

156 / 9 = 17.333 square yards

More information is required to answer this question. Are the tiles 4 inch X 4 inch or 4 ft X 4 ft or 4 cm X 4 cm or some other units?

Multiply the two figures.

First of all we have to convert the dimensions of roof in inches.

1 feet = 12 inches

12 feet = 144 inches

Area of each tile = 4 x 4 inches2

Area of roof = 144 x 144 inches2

So, Number of tiles = Area of roof/Area of each tile = (144x144)/(4x4) = 1296.

-- 14.214 square meters on the floor

-- another 14.214 square meters on the ceiling

-- more square meters on the walls, but to count them up

you need to know the height of the ceiling above the floor

unless an old-school electrician lives in the room, in which case

all of his meters are round

one yard = 3 ft

1 sq yard = 3 x3 = 9 sq ft

496/9 = 55 sq yards

399

292

12 1/12' x 10' = 120.833 sq ft

10 X 10 = 100

15 x 6 = 90 sq ft

With any tile project, you need to estimate 10% waste.

14 x 11.5 = 161

We still need to add 10% for waste so multiply by 1.1

161 x 1.1 = 177.1

You need to purchase 178 tile for a project of this size.

(952 sq ft x 144sq in/sq ft) /(13x13 sq in) = 811.17 tiles

it is a tessellation

The formula is sq ft/ divided by 9 = sq yards. So 667 sq yards. That of course doesn't allow for any waste or cut outs.

182 sq.ft. 182 sq.ft.

160 But buy extra.

13 ft * 24 ft = 312 square feet = 28.99 sq metres.

if you are quoting inches, then a 18x18 tile measures 2.25 square feet. On that basis you would need 106.66 or 107 to the nearest.

Very little

Thirteen

Twice as many as the number of people in the room.

65 feet is a measure of length. Presumably it is an area that needs covering. Also, tiles come in all sorts of sizes.
