The Cylinder
As = 2*pi*r^2 + pi*D*h. = Surface area.
V = pi*r^2 * h.
Cost = As * 0.02/Ft^2.
The Rectangular Prism.
As = 2(L*h + W*h + L*W). = Surface area
V = L * W * h.
Cost = As * 0.02/Ft^2.
NOTES
D = Diameter.
The container with the largest volume
holds the most.
A company is making two types of aluminum containers. One is a cylinder with a height of 1.25 feet and a diameter of 1 foot. The other is a rectangular prism with a length of 0.75 foot, a width of 0.75 foot, and a height of 1 foot. Aluminum costs $.02 per square foot. How much will it cost to produce each type of container? Round to the nearest cent. Which container holds more?
