Answer 1

Correct Question :-

A thickness of pile of 12 cardboards is 65mm ,find the thickness of a pile of 312 such cardboards.

Solution :-

$Given that = \begin{cases}</p><p></p><p>& \text{Thickness of pile of 12 cardboards is 65mm} \\</p><p></p><p></p><p>\end{cases}$

$To find = \begin{cases}</p><p></p><p>& \text{Thickness of a pile of 312 such cardboard} \\</p><p></p><p></p><p>\end{cases}$

• Thickness of the pile of 12 cardboards = 65mm

• Thickness of 1 cardboard = $\huge\frac{65}{12}$

Hence, the thickness of the pile 312 such cardboards = $\huge\frac{65}{12}$× $\huge{312}$

:$\implies$ $\sf\huge{1690mm}$

$\therefore$ The thickness of a pile of 312 such cardboard = $\huge{\red{\boxed{169 cm}}}$
