Answer 2

Answer:

64

Step-by-step explanation:

Given : The thickness of a pile of 16 cardboard is 44 mm.

To Find : how many cardboards will be there in a pile which is 71.5 cm thick?

Solution:

No. of carboards in a pile which is 44 mm thick = 16

No. of carboards in a pile which is 1 mm thick = $\frac{16}{44}$

Now to calculate how many cardboards will be there in a pile which is 71.5 cm thick.

1 cm = 10 mm

71.5 cm = 715 mm

So, No. of carboards in a pile which is 175 mm thick = $\frac{16}{44} \times 175$

                                                                                      = $63.63$

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