Asingle board is 1/12 meter thick. how many boards are there in a stack of boards that is 2 meters high?

Let the number of boards be n.

Since each of them is

meter thick,

All the n boards will be,


meters thick or high.

Since all the board is 2 meters high, it means,


Multiplying through by 12,

n = 2×12

n = 24.

There are 24 boards in the stack.

Alternatively,

Since each board is

meters thick, the number of boards that will be 2 meters high is ;
