Cube

A cube is a three-dimensional shape with six square faces, twelve straight edges, and eight vertices (corners). All the faces of a cube are equal in size and shape, and all the angles between the faces are right angles (90 degrees).

The formula for the surface area of a cube is:

Surface Area = 6 * (side length)²

The formula for the volume of a cube is:

Volume = (side length)³

Where the side length represents the length of one of the sides of the cube.

Cubes are commonly found in everyday objects such as dice, sugar cubes, and certain types of storage containers. They are also used in mathematics and geometry to understand spatial relationships and calculate surface area and volume.

Understanding the properties and formulas related to cubes can help in solving problems related to geometry and spatial reasoning.
