Use the formula: Volume = Base Area × Height
Find the area of the hexagonal base
If the hexagon is regular, use: Base Area = (3√3 / 2) × s²
Let s be the side length of the hexagon
Let h be the height of the prism
Substitute into the volume formula: Volume = (3√3 / 2) × s² × h
If the hexagon is irregular, divide it into simpler shapes and add their areas
Multiply the base area by the prism height to get the volume
Write the final answer in cubic units
