Answer:
C
Step-by-step explanation:
The volume of the regular pyramid is [tex]V=\dfrac{1}{3}A_{base}H.[/tex]
The base of given pyramid is regular hexagon with side 12 cm. The are of this hexagon consistsof area of 6 equilateral triangles and is equal to
[tex]A_{base}=6\cdot \dfrac{1}{2}\cdot 12\cdot 10.4=374.4\ cm^2.[/tex]
Hence, the volume of the pyramid is
[tex]V=\dfrac{1}{3}\cdot 374.4\cdot 36=4,492.8\ cm^3.[/tex]
