The length, width and height of a cuboid are integers, and its volume is exactly 2006cm3. Now, after painting its surface area with red, it is cut into small cubes with side length of 1cm. If there are 178 small cubes with red three sides, there are 178 small cubes with red two sides______ One

∵ there are 178 small cubes with three red sides, ∵ the height of the cuboid must be 1cm, ∵ 2006 = 1 × 2 × 59 × 17, ∵ the length of the cuboid is 59cm, and the width is 34cm, ∵ so there are 114 small cubes with three red sides, 32 × 2 = 64 small cubes with two red sides, and four red cubes with four red sides on the four corners The rest are cubes with red on both sides. 2006-178-4 = 1824
