it's about volume. a refrigerator is 3 ft wide, 2.5 ft deep and 6 ft high. The walls and other parts of the refrigerator take up 20 feet (little 3 on the top I for got the name of it). How many cubic feet are left for food?
note: If you know the answers please explain how you got it. Thank you.

Calculate the volume of the refrigerator and subtract 20 cubic feet.
Cubic feet left for food is:
V = 3*2.5*6 - 20 = 45 - 20 = 25 ft³

the name of the little three is "cubed" and refers to the fact that the number 20 is a measurment of volume (i.e. 3 dimensional in this instance).
Overall volume of fridge = 3 x 2.5 x 6
= 45 cubic ft
cubic feet left = overall volume - allocated volume
= 45 - 20
= 25 cubic feet
good luck at the G&T class!
