Aclosed iron tank 12m long 9m wide and 4m deep is to be made . determine the cost of iron sheet used at the rate of rupees 50 per meter . the sheet being 2m wide

  ₹9600

Step-by-step explanation:

The surface area of the tank is ...

  S = 2(LW +H(L+W)) = 2(12·9 +4(12+9)) = 2(108 +84) = 384 . . . . square meters

If the sheet is 2 m wide, it will take a length of ...

  384 m²/(2 m) = 192 m

At a cost of ₹50 per meter, the cost will be ...

  (₹50/m)·(192 m) = ₹9600

The iron sheet required will cost 9600 rupees.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

step-by-step explanation:

infinity is the answer
