Given pyramid with a regular hexagonal base,
side length=6
cm
Height = 4 cm
We need to find the area of the hexagonal base. First step is to find the apothm,
a=side*(
=6*3/2=9
So the area of each equilateral triangle making up the base
=base*apothem/2
=6 *9/2
=27
The area of base = 6 area of each triangle
=6*27
=162
Volume of pyramid = area of base * height /3
=162*4/3
=216
side length=6
Height = 4 cm
