Find the dimensions of the closed rectangular box with maximum volume that can be inscribed in the unit sphere.

Answer:

Wyjaśnienie krok po kroku:

Załóżmy, że prostokąt ma wierzchołki (x,y,z) w dodatnim oktancie. Prostokątny pudełko musi być symetryczne względem wszystkich trzech osi.

Wtedy jego boki to

$2x,2y,2z$

Objętość = $8xyz$

Maksymalizuj objętość przy założeniu

$x^2+y^2+z^2 =1$

tj. $g(x,y,z) = x^2+y^2+z^2 -1=0$

Użyj mnożników Lagrange'a, mamy

$∇f(x,y,z)=λ∇g(x,y,z)$ przy maksimum

$∇f(x,y,z)=λ∇g(x,y,z) =(8yz,8xz,8xy)\\∇g(x,y,z)=(2x,2y,2z)$

$8yz=2λx8xz=2λy8xy=2λz$

Dzieląc otrzymujemy

$\frac{y}{x} =\frac{x}{y} \\x^2=y^2$

Podobnie $y^2=z^2$

Zatem otrzymujemy $3x^2 =1\\x = \frac{1}{\sqrt{3} }$

Stąd wymiary to

(2x,2y,2z)

$\frac{2}{\sqrt{3} },\frac{2}{\sqrt{3} },\frac{2}{\sqrt{3} } )$

a plane is passed through a parallelepiped, cutting all the lateral edges and forming a right section which is a square. If the

Svet_ta [9500]

The question already provides multiple pieces of information. By utilizing the details given, the answer can be easily arrived at.
Lateral area of the solid = 216 cm^2
Lateral edge of the solid = 9 cm
Let's denote the length of one side of the section as x
Thus,
216 = 4s * 9
216 = 36s
s = 6
From this deduction, it is evident that the length of one side of the section is 6 cm. I trust this answer has been helpful for you.
