Cuboid

Cuboid is a Solid geometrical object, which is defined in 3 d, means we define cuboid in 3 dimension view and proper cuboid definition is– A solid 3 d Geometry, whose all sides are not equal means length, width and height of cuboids are not equal in length and all these sides (length, height and width) of cuboids are define in 3d (3 dimension), that’s why we called cuboid as a 3d structure. Now we discuss geometry of cuboids.

Each cuboid is made by 6 squares which meet at Right Angle means if we connect 6 squares at right angle, then produce geometry is known as cuboid geometry and each cuboid has 8 vertices and 12 edges. Now we discuss formulas for calculating volume and surface area of cuboids:

Volume of cuboids = l * b * h,
Here l is length of cuboid, h is height of cuboid and b is width of cuboid.

Surface area of cuboid = (2 * l + 2 * b + 2 * h),
Here l is length of cuboid, h is height of cuboid and b is width of cuboid,



Suppose, we have a cuboid, whose length is equal to 3 inch, height is equal to 4 inch and width is equal to 5 inch, then,
Volume of cuboid = l * b * h,
                         = 3 * 4 * 5,
                         = 60 inch³.
Surface area of cuboid = (2 * l + 2 * b + 2 * h),                                                
                                                    = (2 * 3 + 2 * 4 + 2 * 5),
                                                    = (6 + 8 + 10),
                                   = 24 inch².
So, volume of cuboid is 60 inch³ and Surface Area of Cuboid is 24 inch², where length is equal to 3 inch, height is equal to 4 inch and width is equal to 5 inch.
