Secret treasure

Scouts have a tent in the shape of a regular quadrilateral pyramid with a side of the base 4 m and a height of 3 m. Find the container's radius r (and height h) so that they can hide the largest possible treasure.

Correct answer:

r =  1.3333 m
h =  1 m

Step-by-step explanation:


Our quadratic equation calculator calculates it.

h=vr 2 v/a=31.3333 2 3/4=1 m
