A tent is constructed in the shape of a pyramid with square base and four faces; each face is
in the shape of an isosceles triangle. The tent is made by cutting away a triangle from each side of a
6 ft x 6 ft silicon-coated polyester and bending up the the resulting triangles to form the walls of
the tent. A steel pole, perpendicular to the base, is placed in the center of the tent for support.

a) Show that the function to be optimized is V(x) = 31x218−32x
where x represents the side length of the square base. Provide an appropriate domain for V .
Fully justify every step of the derivation of the function.
b) Find the maximum volume the tent can have. Fully justify your answer.
