Cube Facts

The video explores five interesting facts about cubes. It begins by defining cubes as three-dimensional shapes with equal height, width, depth, and angles. Examples include dice and ice cubes. The video then discusses cube properties, including its six square faces, 12 edges, and 8 vertices, and mentions that 11 different nets can be formed. The volume of a cube is calculated by cubing the length of one edge. The surface area is found by multiplying the area of one face by six. Finally, the video explains that a cube's defining feature is its 90-degree angles between faces, with opposite planes being parallel.
