working out square meterage ... help please

[Twiglett]

brain-freeze

735 cm long
42cm wide

how many metres square?

is it 3.087 square metres???????

ouch that hurt

I actually think its 30

don't think it could be 3 cos its over 7 metres long

ow .. ow .. ow

I meant thanks Janey

f it's 7.35m long x .42m wide it would be 3 not 30 - like multiplying 7 by a half

really? I am so bad at this

ok another one for you

box of tiles .. each tile is 10 x 10cm and there are 10 in a box .. is that 1 square metre

no

No, that's 0.1 sqm

0.1 x 0.1 x 10

was going to explain - 1m x 1m = 1 sq m - agree?

then 100cm x 100cm = 10,000cm = which = 1 sq m

do you folow?

so 10cm x 10cm x 10 only = 1,000 i.e. 0.1 sq m

so I got the square meterage wrong and the coverage of the tiles wrong

BUT

if I'd done it my way I'd have still ended up with the right number of packs of tiles
