how do u convert cm to sq meters?

Question

wall tiles are packed in boxes of 16 and cost £15 a box. the tiles measure 30cm by 20 cm
How many boxes will be required to cover 5sq meter of wall

Answer 1

.3m x .2m = .06 square metres.
.06 x 16 = .96 square metres in each box.

Answer 2

Firstly, work out what each tile will cover:

30*20cm=600sq,cm

One box will cover (600*16)=9,600sqcm.

1 square metre is 100x100cm. so one square metre is 10,000cm

So 5 square metres is (5*10,000) = 50,000sq cm

Now divide 50,000 by 9,600 = 5.21 (rounded off!)

so you will need 6 boxes (you cannot normally buy a part of a box!

This will cost you £15*6 =£90

(I am presuming you do mean 5 square metres, not 5 metres squared! - that is 25 square metres, and will need 27 boxes at a cost of £405!!!!)

Answer 3

Six boxes. This will give 12 extra tiles as reserve to take care of breakages and for future replacement

Answer 4

you have 5sq m to cover.
you can buy ((30x20)x16)/100 = 0.375sq m per box.
(the 100 is to convert sq cm to sq metres...as 100cm to 1m)
so you will need 5/0.375 = 13.33333recurring boxes
BUT u can't buy 13.33333333 boxes, so you will need 14 boxes (if you do happen to buy 13.33333 boxes, i don't think the salesperson would be very happy...=P)

Answer 5

5 sqm is 50000sq cm

1 tile is 600sqcm

50000/600 = 83.333333 tiles so you need 6 boxes

Answer 6

I suggest you sell bricks by number. Never heard of anyone selling bricks by the square metre. Or if you weigh them, you could sell them by the ton.

Answer 7

1cm x1cm = 1cm^2 = 0.01m x 0.01m = 0.0001m^2

Answer 8

the first answer is correct
