    My teacher never teaches us that how to derive any formula
    She just asks us to write all the formulas
    Then apply them in excercise
    Aaj sach me maja aya kyuki samjh aa rha tha ki formula aakhir ban kese rhe hai
    Thanks 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
    9+2
    =11 m²
    Hence ,the area she wants to paint is 11m².

    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

    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.

    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.

    "Hi Byjus team! I'm Adish, and I just wanted to say how much I've been enjoying your Class 8 Maths sessions. They've been incredibly helpful as I prepare for my upcoming exam on Monday. I was hoping if it's possible to have a revision session before then, focusing on important maths chapters and covering the frequently asked questions in exams. It would be immensely beneficial for my last-minute preparations. Also, a big shoutout to the instructor for delivering such engaging and informative classes, even when I'm watching the older ones. Keep up the awesome work! Thank you!"
    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

    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
