A cube is a 3-dimensional solid figure made by square faces. It would have 8 corners which connects the faces of the cube.
how many faces does a cube have?
There would be 6 faces in a cube
how many other cubes would share a given corner atom or face atom if several cubes were stacked side-to-side, front-to-back, and top-to-bottom?
If several of these cubes are being stacked side-to-side, front-to-back, and top-to-bottom, each corner would share a total of eight cubes. All of the corners would share a different cube. We have eight corners thus eight cubes.</span><span>
