00:00hi kids today we will learn about two shapes cube and cuboid which are 3d

00:10shapes or solid objects

00:16let's first learn about a cube have a look this is a cube now as you already

00:27know what our vertices and edges so let's count its vertices 1 2 3 4 5 6 7

00:418 yeah so a cube has 8 vertices good now let's count its edges 1 2 3 4 5 6 7 8 9

01:0110 11 12 so a cube has 12 edges also all are equal good now it's time to know

01:19what our faces

01:24faces are the individual surfaces of a solid object let's take example of a

01:34dice to learn how many faces does a cube have as a dice is a perfect example of a

01:43cube let's count the faces of a dice which is a cube 1 2 3 4 5 6 yeah six

02:03faces also all faces of a dice are equal and square in shape so now we know that

02:14a cube has six faces which are all equal and square in shape can you find more

02:23objects like a cube in your house try to imagine yeah these are a few objects

02:32that have cube shape so what have we learned we have learned that a cube has

02:428 vertices 12 edges which are all equal and 6 faces which are all equal to and

02:53square in shape good let's learn another 3d shape a cuboid this is a cuboid let's

03:08count its vertices 1 2 3 4 5 6 7 8 yeah 8 vertices good now let's count its edges

03:291 2 3 4 5 6 7 8 9 10 11 12 Wow 12 edges also all the edges of a cuboid are not

03:53equal as in the case of a cube now let's count the faces of a cuboid 1 2 3 4 5 6 so

04:12now we know that a cuboid has six faces can you find more objects like a cuboid in your

04:21house try to imagine yeah these are a few objects that have cuboid shape so what have

04:32we learned we have learned that a cuboid has 8 vertices 12 edges and 6 faces good we have

04:46also learned that both cube and cuboid have 8 vertices 12 edges and 6 faces only difference

05:00is that a cube has all edges and faces equal but not in the case of a cuboid nice now you

05:11may go ahead and take a quiz to learn more bye-bye
