00:07:20उचाई, सब कुछ बराबर है, लंबाई, चोड़ाई, उचाई, सब कुछ बराबर है, लंबाई, चोड़ाई, उचाई, सब कुछ बराबर है, length, breath, height, सब कुछ बराबर है, आप इसमें से किसी को भी length बोल सकते हैं, किसी को भी breath, किसी को भी height, ऐसा नहीं है सर, इसी को length कह

00:07:50this centimeter is also 10 centimeter. So, in any cube,

00:07:54one of three three cubic feet is equal to three cubic feet.

00:07:57And this is 10 centimeter. Yes, exactly.

00:08:00And I have to cut this in 2-2 centimeter small pieces.

00:08:04Who cut this? 2-2 centimeter small pieces.

00:08:08I have to cut this small piece of pieces.

00:08:11I have to cut this big piece of pieces,

00:08:14this bigger cube, this thick piece of pieces.

00:08:18And the small pieces of pieces should be 2-2-2.

00:08:24I have to make 2-2 centimeter small pieces of pieces.

00:08:27So, how can I make 2-2 centimeter small pieces of pieces?

00:08:30First, I am going to cut this piece.

00:08:34This is 10 centimeter.

00:08:38If I make 2-2 centimeter small pieces of pieces,

00:08:41how many pieces of pieces? 5 pieces of pieces.

00:08:44If I make them 2-2 centimeter bigger pieces of pieces of pieces,

00:08:48then I will make them 5 pieces to make them.

00:08:50Now, the five pieces of pieces.

00:09:03doesn't cut Cumbre, which are actually the first cut.

00:09:05Cut!

00:09:06Concur you can handle the diet like this,

00:09:09and this is�로ase, like this cake!

00:09:12Another custom cake is how to cut.

00:09:15Esto is a simple cut!

00:09:18This will be cut again, this will be cut again and this part become way,

00:09:23this is how we are cut again and this is how we are cut again

00:09:26and this is how we cut again

00:09:29This is how we cut until 2 cm makes this way

00:09:32We cut imm hahaha

00:09:33and if I had 4 cut, then I have 1, 2, 3, 3, 4, 5, 5.

00:09:39How many pieces? 5 pieces.

00:09:41The length is 2 cm.

00:09:44So I have 5 pieces to make it.

00:09:47So I have 4 cut.

00:09:52But I have 5 pieces to make it.

00:09:57But I have small cubes not to get it.

00:09:59So smaller cubes if you need it, then you can cut it out.

00:10:03The height of the height is 10 cm.

00:10:06It's 2 cm.

00:10:08It's 5 cm.

00:10:10And it's 5 cm.

00:10:12It's 4 cut.

00:10:15First cut.

00:10:18Third cut.

00:10:20Third cut.

00:10:22And fourth cut.

00:10:24So 4 cut.

00:10:26So 4 cut.

00:10:31This is very big.

00:10:32This is 10 cm.

00:10:34This is 10 cm.

00:10:36This is 2 cm.

00:10:38This is 5 cm.

00:10:40Now this is 5 cm.

00:10:42This is 4 cut.

00:10:44First cut.

00:10:46Second cut.

00:10:48Third cut.

00:10:50Fourth cut.

00:10:52Like this.

00:10:54Now we can see the bigger cubes.

00:10:58This is smaller cubes.

00:11:00This is smaller cubes.

00:11:02This is small cubes.

00:11:04So smaller cubes are too small for you.

00:11:10That's a small shapes.

00:11:11It's big.

00:11:13Small cubes, the little cubes there.

00:11:14So small cubes are so small.

00:11:16I am going to make one cube and make one cube and cut it in smaller cubes.

00:11:26First, I will teach you the cutting concept and then we can solve all these questions without pen and paper.

00:11:34This is a figure and this is a green color cube.

00:11:49This is the dimension of 9.9.9.

00:12:03This is 9.9.9.9 is a cube and cut it in 3-3 cm.

00:12:10It is cut in 3-3 cm.

00:12:13It is cut in 3-3 cm.

00:12:15If you cut it in 2-2 cm.

00:12:18You cut it in 3-3 cm.

00:12:22You cut it in 3-3 cm.

00:12:24It is cut in 3-3 cm.

00:12:29You cut it in the middle of your notebook.

00:12:31You cut it in 3-3 cm.

00:12:33You cut it in 3-3 cm.

00:12:37You can cut it quickly and see if you can cut it or not.

00:12:44This bigger cube is cut in smaller cubes or not.

00:13:07You can cut it quickly and see if you can cut it or not.
