Based on the table attached, the class boundaries are as follows: 43.5, 49.5, 53.5, 59.5, 63.5, 69.5, 73.5, 79.5.

A. Viewing at the frequency table, we find that the lower class limits of two consecutive classes are 40 and 44, respectively. Thus the class width is:
Class width = 44 − 40= 4
B: One can find the class midpoints by putting the average of the lower and upper class limits. So the midpoint of the first class is seen below:
= 40 - 44 = = 42. In a similar way, we find the rest.
C. The Class boundaries is known to be that which separate the classes removing the class limits. The class boundaries are as follows:
43.5, 49.5, 53.5, 59.5, 63.5, 69.5, 73.5, 79.5
Therefore, Based on the table attached, the class boundaries are as follows: 43.5, 49.5, 53.5, 59.5, 63.5, 69.5, 73.5, 79.5.

Answer:
500 cubic feet equals 14158.4 liters or 3740.25 gallons.
Step-by-step explanation:
We are asked to convert 500 cubic feet to liters then to gallons.
We know that one cubic feet equals 28.3168 liters.
We know one liter equals 0.264172 gallons.
Therefore, 500 cubic feet equals 14158.4 liters or 3740.25 gallons.
