• Option (1) 70 cm is correct.

Given :–

• The thickness of a pile of 12 cardboard sheets = 35 mm.

To Find :–

• The thickness of a pike of 240 sheets.

Solution :–

First, we need to find the value of the thickness of a pile of a cardboard sheet.

So,

Given that,

The thickness of a pile of 12 cardboard sheets = 35 mm.

So,

The thickness of a pile of a cardboard sheet =

Hence,

The thickness of a pile of a cardboard sheet is

Now, we have to find the thickness of 240 cardboard sheets =

Now, we have to convert mm to cm.

We know that,

• 10 mm = 1 cm

So,

For converting, we need to divide length value by 10.

We have,

• 700 mm.

Now,

### Hence,

The option (1) 70 cm is correct.
