A candy company is designing a container for its new candy creation.  Consider the cost per cubic centimeter of these three proposed designs.

1.  A pyramid-shaped container with a square base that is 10 cm on each side and with height 20 cm.  This container would cost $5.30.

2.  A cone-shaped container with a radius of 5 cm and height 20 cm.  This container would cost $3.90.

3.  A cylinder-shaped container with a radius of 5 cm and height 15 cm.  This container would cost $7.00.

The least expensive container in terms of cost per cubic centimeter is

• pyramid

• cone

• cylinder
