Answer:-

A cube is a regular solid formed by six square faces, all of the same size. It has 12 edges, and 8 vertices. The cube is the only regular polyhedron which has edges of the same size. It is also known as a hexahedron, although this term is only used loosely, as a regular hexahedron would be a tetragonal dipyramid. The cube is dual to the octahedron – the two forms are duals of each other and have equivalent symmetry.

◉ The surface area of a cube is the sum of the areas of its faces (6 square faces). To calculate the surface area of a cube, multiply the length of the side of the cube by the width of the side of the cube. The surface area of a cube is the sum of the areas of its faces (6 square faces). To calculate the surface area of a cube, multiply the length of the side of the cube by the width of the side of the cube. The formula for the surface area of a cube is Surface area = 6 * side^2. For example, the surface area of a cube with a side length of 2.4 cm is 6 * 2.4^2 cm = 60.96 cm^2.

- Curved/Lateral Surface Area of cube = 4a² = 4(side)²
- Total Surface Area of cube = 6a² = 6(side)²

A quick and easy way to calculate the volume of a cube is by using the formula shown, Simply enter the value for any side of the cube in the proper input box and then press “Calculate.” You will see that your value is now calculated and displayed in a answer box to its with formual of a surface area of cube However, if you make a mistake when entering your values, you can clear all entries from this input box by pressing "Clear" before making your corrections.

**Example :-**Cube of side length = 10 cm , find
surface area of a cube

**Curved surface area = ** 4a² = 4 x (10)² = 400
cm²

**Total surface area = ** 6a² = 6 x (10)² = 600
cm²
