Question
A rectangular box of length x, width Y, and
height z has a surface are of 700 cm². Set-
up the Lagrange equations that will give
the dimension of the box that will
maximize the volume of the box.
O
yz = A (2y + 2x + 700)
x2 = A(2x + 2x + 700)
xy = A(2x + 2y + 700)
2xy + 2yz + 2xz = 700
yz
= 2X (y+z)
xz = 2x(x + 2)
xy=2X(x + y)
xy+yz + xz = 350
yz = λ (2y + 2z - 700)
X(2x + 2x - 700)
XZ =
xy =
X(2x + 2y - 700)
2xy +
2yz + 2xz = 700
yz =
(y +z - 350)
xz =
x(x + z- 350)
xy = x(x + y − 350)
2xy + 2yz + 2xz = 350
