The old pyramid scam gussied up to look like 3-D geometry
[1]
A regular pyramid with a pentagonal base is placed in a sphere.
The pyramid has five congruent lateral sides.
The sphere has a volume of 449841.3724 cubic centimeters.
Find the volume V of the largest possible pyramid that fits inside the sphere.
The first correct answer sent to [email protected] [2] wins a Tucker’s Ice Cream gift card worth a lot of ice cream.
The answer to last week’s puzzle [3] was V = 231.2384 cubic inches.
