In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices.

A perfect cube is a number which is equal to the number, multiplied by itself, three times. For example, 8 is a perfect cube because 3√8 = 2.

Cube, in Euclidean geometry, a regular solid with six square faces; that is, a regular hexahedron. hexahedron. Types of hexahedra.

A cubical box has each edge equal to 10 cm and a cuboidal box is 12.5 cm long, 10 cm wide and 8 cm high. Now, substitute the values of the edge of the cube and length, breadth and height of the cuboid in the lateral surface area of the cube and cuboid and then compare.

[′kyü·bə·kəl ik′span·shən] (physics) The increase in volume of a substance with a change in temperature or pressure.

The three types of thermal expansion are, linear expansion, superficial expansion and cubical expansion.

Table shows some examples of expansion. Railway tracks consist of two parallel metal rails joined together. Small gaps, called expansion gaps, are deliberately left between the rails as there is an expansion of the rails in hot weather. Water expands on heating.

Thermal expansion is the tendency of matter to change in shape, volume, and area in response to a change in temperature. Temperature is a monotonic function of the average molecular kinetic energy of a substance.

Other examples of thermal expansion include: – The air in a car tyre gets warm after a long journey and this increases its pressure. – Railway lines require expansion gaps (similar to bridges) to avoid buckling in hot weather.

Here Are Some Examples of thermal expansion in our Daily Life.

• Cracks in the road when the road expands on heating.
• Sags in electrical power lines.
• Windows of metal-framed need rubber spacers to avoid thermal expansion.
• Expansion joints (like joint of two railway tracks).
