Question

2. CUBOID: Define with diagram, also show the area and volume of it.
Area of Cuboid-2 (1b-bhhl)
Vol of Cuboid lb h​

Answer 1

Answer:

A cuboid is a 3D shape. Cuboids have six faces, which form a convex polyhedron. Broadly, the faces of the cuboid can be any quadrilateral. More narrowly, rectangular cuboids are made from 6 rectangles, which are placed at right angles. A cuboid that uses all square faces is a cube. Properties of a Cuboid are:

It has 12 edges

It has 8 corners or vertices

It has 6 faces.

The basic difference between a rectangle and a cuboid is that one is a 2D shape and the other is a 3D shape.

The basic difference between a cube and cuboid is that a cube has equal length, height and breadth whereas in cuboids these three may or may not be the same. The cuboid can also be called a right rectangular prism.

Where l= length, b= breadth, h= height:

Total Surface Area of Cuboid = 2(l*b+b*h+h*l)

Volume of Cuboid = L*B*H
