Sir please explain about how many circles in more circles
Yes sir please explain
Nice 👍
Thank you! Cheers!
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.
What to do in case of a much larger cube broken into few small and few large cubes

Thank You Sir💥
Thankyou 😇
Tq sir it is very usefull
Can u please explain how these formula came ( (n-2)×12 etc)
@@nazrulhuda9 no sahi hai ye
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
@@yatharthmahoar6154
Yes, you are correct
😂2 min silence for those who use this, formula is wrong
thanks it was very helpful 🤓🤓for @yk7

Thqqq u sooo much for wonderful lecture I understood very well thqqqqq u sir
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 🙏
