Mam please 🥺 give explanation to this IMO question: Class 8 SAMPLE PAPER 01 SECTION 01 LOGICAL REASONING Payal, Honey, Amit, Birju, Deepak, Riya and Firoz are sitting around a circular table, facing the centre. Riya is not second to the left of Deepak and Deepak is not an immediate neighbor of Birju. Amit is third to the right of Firoz. Birju is second to the left of Firoz.
Ma'am, you are really so good. the way you teach is totally mind-blowing. my maths exam is the day after tomorrow and I was not able to understand this topic at all until now. just after one video lecture of yours I really understood it and I think I will remember it now for my whole lifetime. You are a very great teacher indeed. thank you very much for teaching us. your grateful student Tripti Dhanda
Thank you mam for this wonderful session 😀.It was really helpful for me. Answer of HW QUESTION 👇🏻 SOLUTION: Length 'l' of the cabinet = 2 m Breadth 'b' of the cabinet = 1 m Height 'h' of the cabinet = 1.5 m Area of the bottom of cabinet = l × b Since the cabinet is cuboidal in shape, Total surface area of the cabinet = 2(l × b + b × h + h × l). Area of the cabinet that was painted = (Total surface area of the cabinet) - (Area of bottom of the cabinet) = 2(l × b + b × h + h × l) − l × b = 2(b × h + h × l) + l × b = 2 × (1 × 1.5 + 1.5 × 2) + 2 × 1 m² = 2 × 4.5 + 2 m² = 11 m² Therefore the area of the cabinet that was painted is 11 m². SUGGESTION: Mam please bring RD Sharma & Olympiad Questions of this chapter.
*Homework answer* Area of wall painted except the bottom = 2h(l+b) + lb = 2× 1.5 (1+2) + (1+2) = 3 × 3 + 2 = 9 + 2 = 11m² I want the video of ncert solution of chapter 9 algebraic expressions and also of this chapter. Thanks for this amazing session mam 🤩🤩This session was amazing 😊
Thank you ma'am for this amusing class. Solution of the H.W question: LSA of the cuboid = 2h(l + b) =2 x 1.5 (1+2) =3(3) = 9 meter square Surface area of ceiling= l x b = 2 x 1 = 2 meter square Total area covered = 9+2 = 11 meter square Ma'am please bring R.S. Aggarwal solutions.
Name : Poshali Mam Homework Question Solution Length of cabinet = 1m Breadth of cabinet = 2m Height of cabinet = 1.5m Surface area she painted = 2(lb + bh + hl) - lb = Lb + 2bh + 2hl = 1×2+2×2×1.5+2×1-5×1+2+6+3 = 11m sq. Therefore, The Area That surface area did she cover if she painted all except the bottom of the cabinet. = 11m sq.

Master plan for the legends who don't want to study and just want to pass Tmrw is my exam i am not Stu-DYING So 60 marks paper 13 chapter (full book) Plan Study main 2-3 chapter(optional) 6 marks pie chart 6 marks graph Just Prepare this 8 marks mcq ask from your freind in exam from sign language 6+6+8=20 Something which you studied before knowing this plan 20+5-6 marks Total 26 marks 😂🎉 21 is passing Congo you save your time
Do random shit for 5 marks question (atleat 3 questions ) Attempt marks atleat 2 (if they don't give you the marks FIGHT FOR IT) +6 marks 26+6 =31 marks!!! (I'm no master minded girl but ok 🙂)
Please explain how to derive the area of rhombus in your way. I found but i were found it's area by dividing rhombus in four triangles. But i want to find it's area by diving it in two triangles.
Hi maam i am Dyutit bhatt of class viii Total surface area of cabinet =2(lb+bh+hl) =2[(1)(2)+(1)(1.5)+(2)(1.5)] =13 Area of base cabinet =lb=2 Surface area painted =13−2=11m2
Maam The answer is 11m^2. Maam please bring more videos on circles. This session was awesome and my concepts are now clear. You explain so interestingly that i got clear with my doubts
Maam curved surface area of cylinder is also called Lateral surface area of cylinder
It can be called either way
10:24 mam, i have a doubt we divide quadrilateral into 2 triangles , Can we can divide into 4 also by making another diagonal also ?
Yes you can, but it will be more work
Formula will be… 1/2 x b x d1 x d2 x d3 x d4
D1, d2, d3 and d4 being the diagonals and b being the common length

By The Way here is the homework answer:
l=2m
b=1m
h=1.5m
LSA of Cuboid=2h*(l+b)
=2*1.5*(2+1)
=3*3
=9m^2
Area of the top =(l*b)
=2*1
=3^2
.:. Area Painted = LSA of the cuboid+Area of the top
=9+2
=11m^2

I really liked this session it was very useful.. ❤
You teach very nice.
Thank you so mam... 😇
1:28:42 required surface area = 2(hl +bh)+lb
2(1.5*1 + 1.5*2 )+2
2(1.5+3)+2
2(4.5)+2

Hence ,the area she wants to paint is 11m².

Answer of HW QUESTION 👇🏻
SOLUTION:
Length 'l' of the cabinet = 2 m
Breadth 'b' of the cabinet = 1 m
Height 'h' of the cabinet = 1.5 m
Area of the bottom of cabinet = l × b
Since the cabinet is cuboidal in shape,
Total surface area of the cabinet = 2(l × b + b × h + h × l).
Area of the cabinet that was painted = (Total surface area of the cabinet) - (Area of bottom of the cabinet)
= 2(l × b + b × h + h × l) − l × b
= 2(b × h + h × l) + l × b
= 2 × (1 × 1.5 + 1.5 × 2) + 2 × 1 m²
= 2 × 4.5 + 2 m²
= 11 m²
Therefore the area of the cabinet that was painted is 11 m².
SUGGESTION: Mam please bring RD Sharma & Olympiad Questions of this chapter.
mam please bring NCERT and RD sharma solutions of both chapters
Kuch samach nahi aaya
*Homework answer*
Area of wall painted except the bottom
= 2h(l+b) + lb
= 2× 1.5 (1+2) + (1+2)
= 3 × 3 + 2
= 9 + 2
= 11m²
I want the video of ncert solution of chapter 9 algebraic expressions and also of this chapter.

Solution of the H.W question:
LSA of the cuboid = 2h(l + b)

=3(3)
= 9 meter square
Surface area of ceiling= l x b

Length of cabinet = 1m
Breadth of cabinet = 2m
Height of cabinet = 1.5m
Surface area she painted = 2(lb + bh + hl) - lb
= Lb + 2bh + 2hl
= 1×2+2×2×1.5+2×1-5×1+2+6+3

36=BD²
√36=BD
6=BD
You applied Pythagorean theorem.
