Cuboid

A cuboid is a 3D rectangular prism with six faces, all parallelograms. A cuboid is a polygon with three to twelve vertices. A cuboid has 8 edges and 12 corners. The length, width, and depth of a cuboid are called the dimensions of the cuboid. A cuboid has two kinds of diagonals: the minor diagonal, which runs from the lower left corner to the upper right corner, and the major diagonal, which runs from the lower left corner to the upper left corner. A cuboid is a special kind of parallelepiped. A cuboid can also be called a rectangular box.

Cuboids are the 3D analogs of parallelepipeds (rectangular solids), which are the 3D analogs of boxes. A cuboid has six rectangular faces (though not all rectangular faces are cuboids; see below). The cuboid is the 3-dimensional case of the parallelepiped, a box-like shape that has six faces. A cuboidal body has six faces which are parallel and equilateral parallelograms. The difference between a cuboid and a rectangular prism is that the former has edges of equal length, while the latter has parallel top and bottom faces. Cuboids are used to build walls, floors, ceilings, and roofs. Cuboids are also known as rectangular parallelepipeds.

💡 A cuboid is shown in the figure with length 'l' , bredth 'b' and height 'h'.

Cuboid formula:-

  • Volume of a cuboid = lbh
  • Diagonal of cuboid = √(l² + b² + h²)
  • Curved/Lateral Surface Area = 2(lh + bh)
  • Total Surface Area = 2(lh + bh + lb)
  • Where l-length, b-breadth,h-height

How to use cuboid calculator ❓

Enter cuboid length, breadth and cuboid height values into the appropriate input fields and then click calculate button. All values will appear in the answer box with formula and image of a cuboid. If you need to calculate another cuboid value simply clear all input fields with help of a clear or erase button and then re-enter all parameters for dimensions once again.

How to solve cuboid question ❓

Example.1:- A room has 16m length, 14m breadth and 7m height then find its volume of room and surface area of the room?

Answer => l→ 16 m, b→ 14 m, h→ 7 m

Volume = lbh = (16 x 14 x 7) m³ = 1568m³

Total Surface Area = 2(lh + bh + lb) = [2(16 x 14 + 14 x 7 + 16 x 7)] cm² = (2 x 434) cm² = 868 cm²
