Please explain this question a solid cube of 4 inches has been painted red green black one pair of opposite faces it has been then cut into 1 inch cubes questions 1) how many cubes have no faces painted 2) how many cubes have three faces painted 3)how many cubes have only four faces painted 4) how many cubes have only one face painted Please say like these problems and say answer sir
343 cubes of similar size are arranged in a form of bigger cube abd kept at the cornor of a room, all the exposed sides are painted then how many cubes have atleast 2 sides painted?
Thankyou sir. Can add Number of total cuts=(N-1)×3 Number of surfaces painted four side =0 as these types of questions also have been asked in some exams 👍
There is not a single doubt left when I watch your video sir….. you are really my mentor…. Thanks for sharing amazing ideas with students👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻
If you visualize it then it would be easy for you to understand Ans: cubes which are 2 faces colour are on edge except two at corners which have 3 colour so to remove them we subtract 2 (n-2) for each edge and there are 12 edges so we multiply by 12 and we get formula (n-2)×12
3 colored sides = 8, 2 colored sides = 4*(a+b+c-6), 1 colored side = 2*[(a-2)*(b-2)+(b-2)*(c-2)+(a-2)*(c-2)], 0 colored side = (a-2)*((b-2)*(c-2) these apply only when each side is cut.
Sir, could you please esplain this question - A cube of side 5 cm is painted on all its side. If it is sliced into 1 cubic centimeter cubes, how many 1 cubic centimeter cubes will have exactly one of their sides painted. Thank You

Thankyou sir. Can add
Number of total cuts=(N-1)×3
Number of surfaces painted four side =0 as these types of questions also have been asked in some exams 👍
Your starting was very good about the concept of cutting along the length .. this was not told by any teacher in any video

What to do in case of a much larger cube broken into few small and few large cubes
Can u please explain how these formula came ( (n-2)×12 etc)

Yes, you are correct
😂2 min silence for those who use this, formula is wrong
Nice 👍
Thank you! Cheers!
Thank u sir plz upload more vdos
Thank you sir nice explaination
Sir Please Explain same Concept in case of Cuboid.
Hearty Request
3 colored sides = 8, 2 colored sides = 4*(a+b+c-6), 1 colored side = 2*[(a-2)*(b-2)+(b-2)*(c-2)+(a-2)*(c-2)], 0 colored side = (a-2)*((b-2)*(c-2) these apply only when each side is cut.
Thank you very much Sir
Thank you sir

If we have all side painted then how to solve it sir
@@divyabharahtiperiasamy9413 all the sides can be painted only if there is only 1 cube

Sir, could you please esplain this question - A cube of side 5 cm is painted on all its side. If it is sliced into 1 cubic centimeter cubes, how many 1 cubic centimeter cubes will have exactly one of their sides painted. Thank You
I think the answer is 34. I am not sure. I used the equation[n-2]^2*6. but I am confused with the statement '1 cubic cm'
we need for 1 side painted, hence the formula which will be used should be (n-2)*12 = (5-2)*12 = 3*12 = 36
54ans
Total no. of cubes = 125
Let n=5
No. Of cubes with one side painted= (n-2)^2 * 6
= 3^2 * 6 = 54
Hope it helps!🙃
Using the formula, we get 54.
Very useful and very easy
Thanks 🙏
Thank you sir that was easy to understand
Thankyou sir 😇✨ it’s a great one
