A box with a square base and no top is to be built with a volume of 1638416384 in33. Find the dimensions of the box that require
julsineya [31]

Answer:

512\ \text{in}^2

Step-by-step explanation:

x = Length and width of base

y = Height of box

Volume of the box is 16384\ \text{in}^3

x^2y=16384\\\Rightarrow y=\dfrac{16384}{x^2}

Surface area is given by

s=x^2+4y\\\Rightarrow s=x^2+4\times \dfrac{16384}{x^2}\\\Rightarrow s=x^2+\dfrac{65536}{x^2}

Differentiating with respect to x we get

s'=2x-\dfrac{131072}{x^3}

Equating with 0 we get

0=2x^4-131072\\\Rightarrow x=(\dfrac{131072}{2})^{\dfrac{1}{4}}\\\Rightarrow x=16

s''=2+\dfrac{393216}{x^4}

at x=16

s''=2+\dfrac{393216}{16^4}=8>0

So the function is minimum at x = 16

y=\dfrac{16384}{x^2}=\dfrac{16384}{16^2}\\\Rightarrow y=64

The material required is

s=x^2+4y=16^2+4\times 64\\\Rightarrow s=512\ \text{in}^2

The minimum amount of material required is 512\ \text{in}^2.
