What is a 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.
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 solve the 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
How to use the cuboid calculator
Enter the 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 a formula. 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.
