Answer:
21,800 milliliters
Step-by-step explanation:
Here's a trick.
King Henry Died By Drinking Chocolate Milk.
King = Kilo, Henry = Hecto, Died = Deka, By = Base (liters, grams, meters), Drinking = Deci, Chocolate = Centi, Milk = Milli.
This helps to remember the order so you can move the decimal over the proper amount of times.
If you are starting at the base, and need to move to milli, you will move the decimal place 3 places to the right.
So for 21.8 liters = 21,800 milliliters

Answer:
(9√3 -3π/2) ft^3 ≈ 10.88 ft^3
Step-by-step explanation:
The area of the hexagon is given by the formula ...
A = (3/2)√3·s^2 . . . . for side length s
The area of the hexagonal face of this solid is ...
A = (3/2)√3·(2 ft)^2 = 6√3 ft^2
__
The area of the circular hole in the hexagonal face is ...
A = πr^2
The radius is half the diameter, so is r = (2 ft)/2 = 1 ft.
A = π(1 ft)^2 = π ft^2
Then the area of the "solid" part of the face of the figure is ...
A = (6√3 -π) ft^2
__
The volume is ...
V = Bh . . . . . where B is the area of the base of the prism, and h is its height
V = ((6√3 -π) ft^2)(3/2 ft) = (9√3 -3π/2) ft^3 ≈ 10.88 ft^3
