Try this :

int noOfRow = total/2 + ceil((total % 3)/3.0);

A faster method might be:

Notice in the divide by 2 method, most numbers work. The ones don't work are: 2, 4, 8, 10... basically, even numbers that aren't divisible by 6.

So we can come up with something like:

int count = array.count;
if (count % 2 == 0 && count % 6 != 0) {
    count + 2;
}
int rows = ceilf(count / 2);

Or we can write a for loop:

int counter = array.size;
int rows = 0;
int dec = 1;

while (counter > 0) {
    rows++;
    counter - dec;
    dec = dec % 3 + 1;
}

The for loop is of course, slower.

Simple logic for this is:

NoOfRows = TotalCount / 2

For e.g.: 

If last value is 6 then, total no of rows are (6 / 2) = 3
If last value is 12 then, total no of rows are (12 / 2) = 6

You have to think logical that's it.

Hope this helps.
