Using v= Iwh, what is an expression for the volume of the following rectangular prism
2 answers:
Alrighty, so...
We know that the volume of a prism is equal to its length times its width times its height <em> </em><em>( V= L * W *H )</em>
For example, if we were given a problem in which we are given each of those variables, all we have left to do is plug each one of them into the equation above!
Solving for your answer would hypothetically look like this:

66.5
70.5
c.
Class boundaries
44.5-48.5
48.5-52.5

57.5-60.5
60.5-64.5
64.5-68.5
68.5-72.5
Step-by-step explanation:
There are total 7 classes in the given frequency distribution. By arranging the frequency distribution into the refine form we get,
Class
Interval frequency
45-48 1
49-52 3
53-56 5
57-60 11
61-64 7
65-68 7
69-72 1
a)
Class width is calculated by taking difference of consecutive two upper class limits or two lower class limits.
Class width=49-45=4
b)
The midpoints of each class is calculated by taking average of upper class limit and lower class limit for each class.
Class
Interval Midpoints
45-48
49-52
53-56
57-60
61-64
65-68
69-72
c)
Class boundaries are calculated by subtracting 0.5 from the lower class limit and adding 0.5 to the upper class interval.
Class
Interval Class boundary
45-48 44.5-48.5
49-52 48.5-52.5
53-56 52.5-56.5
57-60 56.5-60.5
61-64 60.5-64.5
65-68 64.5-68.5
69-72 68.5-72.5
Based on that table of values, we know the highest point(vertex) is at 0.9, 5.9
we can also use just one another point... say 1.4, 4.6
we can also use just one another point... say 1.4, 4.6
