:
Find the dimension that maximize the surface area.
A rectangular box without a lid should be made with 12m2 of
cardboard. What are the dimensions of the box that maximize the
volume?
a.) 2m x 2m x 2m
b) 1.54m x 1.54m x 0.77m
c) 2m x 2m x 1m
d) 4m x 4m x 2m
An open-top rectangular box has a volume of 250 cm 3. The width
of the box is 5 cm. The cost is $2/ cm 2 for the base and $1/ cm 2
for the other sides. What is the minimum cost for making the
box?
We are tasked with constructing a rectangular box with a volume
of 1313 cubic feet. The material for the top costs 1010 dollars per
square foot, the material for the 4 sides costs 22 dollars per
square foot, and the material for the bottom costs 99 dollars per
square foot. To the nearest cent, what is the minimum cost for such
a box?
A rectangular box with a square base and an open top and a
volume of 1ft^3 is to be made. Suppose the material used to build
the sides cost $4 per ft^2 and the material used to build the
bottom costs $1 per ft^2. Determine the dimensions (i.e. the
side-length of the base and the height) of the box that will
minimize the cost to build the box.
Note: if we let x denote the side-length of the base and...
A company plans to design an open top rectangular box with
square base having volume 4 cubic inches. Find the dimension of the
box so that the amount of materiel required for construction is
minimal.
(a) Find the dimension of the box so that the amount of materiel
required for construction is minimized.
(b) What is the minimized material required for the
construction?
A rectangular box with no top is to be made to hold a volume of
32 cubic inches. Which of following is the least amount of material
used in its construction?
a.) 80 in2
b.) 48 in2
c.) 64 in2
d.) 96 in2
You want to build a rectangular box in such a way that the sum of the length, width and height is 24 cm.
a) Define the equations so that the dimensions of their volume are maximum
b) Which of the equations proposed would be the restriction and which function? Explain
c) Using the technique you want to calculate maximums and minimums, what are these values? What volume will the box have?
A rectangular box is to have a square base and a volume of 40
ft3. If the material for the base costs $0.35 per square
foot, the material for the sides costs $0.05 per square foot, and
the material for the top costs $0.15 per square foot, determine the
dimensions of the box that can be constructed at minimum cost.
