1. Ming Yao bought a magic box as shown in the left diagram. The box is a cuboid with a removable cube at the top right corner. The entire magic box can exactly hold 20 small cubes like that. When Ming Yao performs magic, he removes the cube and moves it to the top of the box, as shown in the right diagram. At this point, the surface area of the box increases by 676 cm2. What is the volume of the magic box? (Give your answer in cm³)
