Determine the dimensions of a rectangular solid (with a square base) with maximum volume if its surface area is 529 square meter

Zielflug [23.3K]

Answer:

$x=23/\sqrt{6}$ ,

$y= \frac{23}{6\sqrt{6}}$

Step-by-step explanation:

From the question we are told that

Surface area is 529 square meters

Generally the dimensions of the cuboid

$v=x^y$

$D=4xy+2x^2 =529$

$V=x^29(\frac{529-6x^2}{4x})$

$V' =529-6x^2/4$

$v'=0$

Therefore

$529=6x^2$

$x=\sqrt{\frac{529}{6} }$

$x=23/\sqrt{6}$

Mathematically

$v''=\frac{12x}{4}$

$v''=-3\frac{23}{\sqrt{6} }$

$y= \frac{529-2*(\frac{529}{6} }{4*\frac{23}{\sqrt{6} } }$

$y= \frac{23}{6\sqrt{6}}$

Therefore

$x=23/\sqrt{6}$

and

$y= \frac{23}{6\sqrt{6}}$

Answer:

We are given a height and radius for a cylinder and we must determine what the surface area is. Surface area is the area that is showing all around the shape. So it would include the area of the top and bottom circles and also the entire strap around the cylinder. Using the equation below we can find the surface area.

$S = 2\pi rh+2\pi r^2$
