Question

If the thickness of a pile of 16 cardboards is 44mm , how many cardboards will be there in a pile which is 71.5 cm thick ?

Answer 1

Hey mate,.

Thickness of 16 cardboard = 44mm

Thickness of 1 cardboard =44/16=2.75mm

Given file thickness=71.5cm=715mm

The number of cardboard required=715/2.75=268.86

Which is not a whole number so we have to round it off

Therefore number of cardboard required =269 cardboard

Hope it will help you

Answer 2

$\blue{Solution}$

since 1mm = 0.1cm

then, 44mm= 4.4cm

Now,

in 4.4cm there are 16 cardboards

in 71.5cm__________ (16/4.4)×71.5=260 cardboards.
