Answer:
The maximum height of the prism is
Step-by-step explanation:
Let
x------> the height of the prism
we know that
the area of the rectangular base of the prism is equal to
so
-------> inequality A
------> equation B
-----> equation C
Substitute equation B in equation C
------> equation D
Substitute equation B and equation D in the inequality A
-------> using a graphing tool to solve the inequality
The solution for x is the interval---------->
see the attached figure
but remember that
The width of the base must be meters less than the height of the prism
so
the solution for x is the interval ------>
The maximum height of the prism is
