The pyramid top has a height of 9 feet, and the entire obelisk as a height of 60 feet, the width of the base is 7 feet what is the volume of the obelisk in cubic feet?

The volume of the obelisk will be given by:
V=(volume of pyramid)+(volume of cuboid)
volume of pyramid will be:
1/3(base area)*height
=1/3*9*7*7
=147 cubic ft

volume of the cuboid will be:
volume=(length*width*height)
v=(7*7*(60-9))
v=2499 cubic ft
total volume of the obelisk will be:
V=(2499+147)=2446 cubic feet
