Carefully arrange 12 rows with 8 coins in each row.
You could make an L shape out of three coins, and place the fourth on the corner. That way there are three coins up and three across.

This is only possible if you allow adding coinsNumber of coins in row x Number of rows = total number of coins5 x 2 = 10 coins4 x 4 = 20 coinsYou would need 10 more coins
Carefully arrange 12 rows with 8 coins in each row.
If you think 2D you can stack one coin on top in a row.
3 1 1 1 1 1 1 The drawing above, if it is preserved by the formatting, illustrates how. For the first row, put on 4 coins in a row. Stack two additional coins on top of one of the coins. For the second row, make it perpendicular to the first row, and overlapping the stack of 3 coins. You have used a total of 9 coins, with the stack of 3 coins doing double duty for both rows.

Form a triangle with the six coins. Now you have 3 rows with 3 coins in each row!
