The volume of a regular hexagonal prism is
. So, the closest option is

To find the volume of a regular hexagonal prism, you can use the formula:
Volume=

In this case, the side length of the regular hexagon is given as 4 cm, and the height of the prism is also 4 cm. Plug these values into the formula:
Volume=

Volume=

Volume=

Volume=96√3
Now, you can calculate the numerical value:
Volume≈ 1

So, the closest option is 1. 166.3
