The volume V of a prism can be found by:
The volume of a rectangular prism can be found through:

Where l is the length, w is the width, and h is the height.
The height can be found by rearranging the equation to:

Take the volume (1374.28) and divide it by the length times the width (9.4*17.2=161.68).
1374.28/161.68=
8.5 inches is the height of the prism.
Answer:
C
Step-by-step explanation:
4 p.m to 8 p.m is 4 hrs.....so she worked 4 regular hrs
8 p.m. to 1 a.m is 5 hrs...she she worked 5 hrs for 1.5 times as much
4x + 5(1.5x) = 92
4x + 7.5x = 92
11.5x = 92
x = 92 / 11.5
x = 8 <==== so she charged $ 8 per hr from 4 pm. to 8 pm. and (8 * 1.5) = $ 12 per hr for hrs after 8 p.m
To find the mean you add all the numbers then divide by how many numbers there are :
8+16+12+11+8=55
in the equation there are 5 numbers, so you divide 55 by 5 :
55÷5=11
the mean is 11
hope this helps
