# Cube and cubic formula ## What is a cube? Answer – The solid whose all faces are a square is called a cube. A cube has a total of 6 surfaces.

Volume of Cube-l³ Cubic unit

Total surface area of the cube-6×l² Square unit

Diagonal of cube-√3×l unit

## What is cuboid? A solid whose all faces are an import is called a cuboid. A cuboid has a total of 12 edges.

Volume of cuboid-Length × Width × Height (l × b × h) Cubic unit

Diagonal of cuboid-√l² + b² + h² unit

Area of total page (entire) of cuboid-2 (length × width + width × height + height × length) square unit

## If the box is covered

Inner length = outer length – 2 × thickness

Inner width = outer width – 2 × thickness

Inner height = outer height – 2 × thickness

## If the box is not covered

Inner length = outer length – 2 × thickness

Inner width = outer width – 2 × thickness

Inner height = Outer height – × thickness

### If all the sides of the cube or cuboid are multiplied by k

(a) The surface area k will be multiplied and

(b) Volume will be multiplied
