Question

How many cards can be made out of a sheet of paper measuring 324 cm by 144 cm, if each
card requires a piece of paper of size 16 cm by 12 cm?
​

Answer 1

The total number of cards made out from the sheet of paper is 243.

The dimensions of the sheet is given as 324 cm × 144 cm.

Length of the sheet = 324 cm

Breadth of the sheet = 144 cm

We have to find the number of cards of dimensions 16 cm × 12 cm can be made from the sheet of paper.

Area of the sheet of paper = 324 × 144

Area of the sheet of paper = 46656 sq. cm

Now are of one card = 16× 12

Now arer of one card = 192 sq. cm

Now number cards made from the sheet of paper $\frac{Area \ of \ sheet \ of \ paper}{Area \ of \ the \ card}$

Number cards made = $\frac{46656}{132}$

Number cards made = 243
