11x15, stacked and then cut in half to make 5 x14. Then the front of the truck was cut into 5x5 and the back into 5x9. The sliver middle, in between the truck, is a 2" foam block. All is covered with fondant and the accents are F/G. The cake is not on the sliver board. I put the cake on a thin wood board. Then the thin wood board is on 6 1x1 wooden dowels that are hot glued to the sliver board. This gives the appearance that the Fire Truck is standing on the tires.
