Habakkuk wants to design an open rectangular box with the volume of 20 ft^3 such that the base has length twice the width. The material for the base costs Php 20.00 per square foot while the material for the sides costs Php 8.00 per square foot. What is the minimum cost of the materials to be used for the box.
Cylinders
A cylinder is a three-dimensional solid shape with two parallel and congruent circular bases, joined by a curved surface at a fixed distance. A cylinder has an infinite curvilinear surface.
Cones
A cone is a three-dimensional solid shape having a flat base and a pointed edge at the top. The flat base of the cone tapers smoothly to form the pointed edge known as the apex. The flat base of the cone can either be circular or elliptical. A cone is drawn by joining the apex to all points on the base, using segments, lines, or half-lines, provided that the apex and the base both are in different planes.
Please help me with this.
