estimate how many 20 cm x 20 cm tiles it would take to tile the floor and three sides of a shower stall.?

Question

the stall has a square floor, 16 square feet, and five foot walls. please provide a detailed explanation =) best answer gets 10 pts!!

Answer 1

ok floor is 4ft by 4ft = 122cm x 122cm = 15,000 cm^2 approx
walls are 4ft by 5ft = 122cm x 152cm = 18,600 cm^2 approx

(1 x floor) + (3 x walls) = 15,000 + 55,800 = 70,800 cm^2

each tile is 20 cm x 20cm = 400cm^2

Tiles required = 70,800/400 =177

Always get 10% extra for breakages and cutting making 194. Get 200!!!

Answer 2

Your floor has area 600 cm x 400 cm = 240000 cm² Each tile has area 20 cm x 20 xm = 400 cm² Therefore you need 600 tiles. However, you must account for 2% breakage, so 600 = .98 X X = 613 tiles Now if you break 2%, you have exactly 600 tiles left to tile the floor.

Answer 3

The first answer is incorrect.

Total area is 16 + 3*5*4 = 16+ 60 = 76 square feet.

Assuming 30cm = 1 foot, you can tile the floor with 6 x 6 = 36 tiles, since the floor is 4ft by 4ft.

Each wall requires 150cm by 120cm, that is 6*7.5 = 45.

So total tiles required are 36 + 45 + 45 + 45 = 171.

Answer 4

Well, a square floor that's 16 square feet, is 4 feet on a side. That's 121.92 cm for a total area of 14,864.49 cm2.

The walls are 5x4 feet or 121.92 X 152.4 cm = 18,580.61 cm2 .

So the total area to be tiled is (18,580.61 x 3) + 14,864.49 = 70,603.31 square cm.

The tiles are 400 cm2

70603.31/400 = 176.5

So you need at least 177 tiles. Probably more to allow for selvage.

Answer 5

area of floor= 16 sq ft
so each side =4 ft

area of 3 walls= 3 x 4 x 5 =60 sq ft

total area=76sq ft

1 sq feet = 922.9444 sq cm
so 76 sq feet = 70143.7744cm^2

area of tile = 20x20 =400sq cm

total tiles required = area of floor and walls / area of 1 tile

=70143.7744 /400= 176 tiles

Answer 6

you need to allow 3mm either side of the tile so its going to be 20.6 per tile also you must devide the area into square block sections with the cut tiles leaving a boarder allways start at the focal point to allow maximum useage but to be honest if you have never done it befor its best to work with someone who has and failing that B&Q have a good leaflet on how to tile

Answer 7

1 inch = 2.54 cm
20 cm cx 20 cm tiles = 7.87 inch x 7.87 inch tiles (20 /2.54 = 7.87)
______________________

The total area to be tiled is the surface area of a cube MINUS the top

Surface area = 16 sq. ft (floor) + 3 ( 4 x 5)
S = 16 + 60
S = 76 sq. ft
_____________

1 sq. ft = 144 sq. inches ( 12 x 12)
76 sq. ft = 76 x 144 = 10,944 sq. in.
______________________
Since one 20 cm x 20 cm tile = 61.94 sq. inches tile,

we need 10,944/61.94 = 176.69 pieces or
177 pieces.

However, in reality you need more than this because of breakage and for portion that need to be cut.
