It is assumed the base of the prism is a square wit side of 5 cm.
<u>The volume is:</u>
<u>The base is:</u>
<u>Find h:</u>
You can see 84.78 as
.
So, you can see the problem as 
First, multiply all the numerators together and all the denominators together.
You end up with 
=33.912
Answer:
Step-by-step explanation:
The volume of a rectanguiar shape like this one is V = L * W * H, where the letters represent Length, Width and Height. Here L is the longest dimension and is 28 - 2x; W is the width and is 22-2x; and finally, x is the height. Thus, the volume of this box must be
V(x) = (28 - 2x)*(22 - 2x)*x
and we want to maximize V(x).
One way of doing that is to graph V(x) and look for any local maximum of the graph. We'd want to determine the value of x for which V(x) is a maximum.
Another way, for those who know some calculus, is to use the first and second derivatives to identify the value of x at which V is at a maximum.
