Question

How many envelopes cn be made out of a sheet of paper 384 cm by 172 cm , if each envelope requires a piece of paper of size 16 cm by 12 cm

Answer 1

Answer

344 envelope

Solution

In the questions given dimensions of sheet of paper length 384 cm breadth 172 cm.

first we find Area of the sheet of paper= length × breadth

Area of the sheet of paper = l×b

$384 \times 172 = {66048cm}^{2}$

Now we find area of each each envelope .

Here given dimensions a piece of paper of size length 16 cm breadth 12 cm.


Area of each envelope Sheet paper = length × breadth

$16cm \times 12cm = {192cm}^{2}$

Now we find How many envelopes can be made out of a sheet of paper.

Again

$\frac{area \: of \: the \: sheet \: of \: paper}{area \: of \: each \: sheet \: of \: envelope} \\ \\ \frac{ {66048cm}^{2} }{ {192cm}^{2} } \\ \\ = 344 \: envelope$
