Abox with a square base and no top is to be built with a volume of 4000 in3. find the dimensions of the box that requires the least amount of material. how much material is required at the minimum?

Let the length of the square base be x inches .

And the height of the box be y inch .

Volume = x*x*y

4000 = x *x *y

S = x*x + 2xy + 2 x y

S ' =0

x = 20

3x^3-x^2+6x-9

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
