**Idk**

the answer should be 6,

the total "power" (as I like to call it) is 4 x 18, which is 72.

You divide that by 12, giving you six.

The calculator is wrong. Six pavers are needed.

Re @idk

4 * 18 = 12(4+n)

72 = 12(4+n)

-----------------

12

6 -4 =4 - 4+n

6 - 4 = n

2 = n

4 * 18 = 12(4+n)

72 = 12(4+n)

-----------------

12

6 -4 =4 - 4+n

6 - 4 = n

2 = n
