Question

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

Answer 1

Thickness of $16$ cardboard $=44$mm

Thickness of $1$ cardboard $=\frac{44}{16}$

$=2.75$mm

Given file thickness $=71.5$cm $=715$mm

The number of cardboard required $=\frac{715}{2.75}$

$=260$

Therefore, number of cardboard required $=260$.
