Answer 1

Given:

The thickness of one board is 11/3 cm

To find:

The height of the stack.

Solution:

We have the 9 board in one stack

So in the height of the stack the thickness of the board will be added to make the complete stack of 9 boards.

So the height of the stack will be given by:

• H = 9×11/3
• H = 3×11
• H = 33 cm

The height of the stack is 33 cm.
