A cube is a three-dimensional solid with six equal square faces, 12 straight edges, and 8 vertices, so it can be distinguished from solids whose faces are rectangles or other shapes. Identifying cubes requires attending to these defining attributes rather than the solid’s size, color, or orientation; more advanced properties such as volume and surface-area calculations are not included.
A cube is a solid shape with:
To identify a cube, look at its faces. The faces must all be equal squares. Its size, color, or position does not matter.
Example:
A shape has faces. Each face is a square, and all the squares are the same size. Is it a cube?
Step 1: Look at the faces.
They are all squares.
Step 2: Check that the squares are equal.
They are all the same size.
Step 3: Decide.
Yes, the shape is a cube. It also has straight edges and vertices.
A box with long rectangular faces would not be a cube, even if it has faces.
