A cuboid wood block, cut from the top of the cuboid 5 cm high, the rest is a cube, the surface area reduced by 120 square centimeters______ Cubic centimeter

The original cuboid's length and width are: 120 △ 4 △ 5, = 30 △ 5, = 6 (CM); the original cuboid's height is: 6 + 5 = 11 (CM); the original cuboid's volume is: 6 × 6 × 11 = 396 (cm3); answer: the original cuboid's volume is 396 cm3. So the answer is: 396
