(4) Cylinder

Answer 1

A door is a solid object. And too it is a material. Therefore we have studief that all solids have a shape and the door is of cuboid shape . Thus , your answer is cuboid

Answer 2

Answer : (2) Cuboid

____________________________

Cuboid :

_______________

A shape which has 6 rectangular faces, 8 vertices and 12 edges is called Cuboid and from the definition of Cuboid we can get the shape of a door will be Cuboidal because the door has also 6 rectangular faces, 8 vertices and 12 edges.

Some points to remember about Cuboid :

_______________________________

• Total Surface Area of Cuboid :

-------------------------------------------

2(lb+lh+bh)

• Volume of Cuboid :

-------------------------------

l × b × h

• lateral Surface Area :

---------------------------------

2h(l+b)

where l = Length, b = Breadth and h = Height of the Cuboid.
