3D Shapes - Cube And Cuboid
Transcript
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
