Question

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

Answer 1

Answer:

• Thickness of a pile of 16 cardboards = 44 mm.

Here we need to find total cardboards in a pile which is 71.5 cm thick.

As we know that,

• 1 cm = 10 mm.

So,

• 71.5 cm = 715 mm.

Number of cardboards = 16/44 × 75

→ 63.63 cardboards.

Hence, approx 64 cardboards will be there in a pile which is 71.5 thick.

Answer 2

$\bf{\red{\underline{Given}}}\::$

➜ The thickness of pile of 16 cardboards is 44mm

$\bf{\orange{\underline{Need\:To\:Find}}}\::$

➛ No. of cardboards which is there in a pile of 71.5cm thick

$\bf{\purple{\underline{Solution}}}\::$

➨ No. of cardboards in a pile which is 1mm thick = $\dfrac{16}{44}$

We Know That,

$\red{\begin{cases}\rm{1cm \ = \ 10mm} \\ \rm{71.5cm \ = \ 715mm}\end{cases}}$

$\bf\blue{Hence,}$

No. of cardboards in a pile which is 715mm thick :

➸ $\dfrac{16}{44} × 715$

➸ $\bf\pink{63.63}$

∴ 64 cardboards will be there in a pile which is 71.5cm thick
