A cubic yard is any volume of material that is 3 feet long by 3 feet wide by three feet deep, or 3â² X 3â² X 3â². To find how many cubic yards you will need multiply the length times the width times the depth and divide by 27.

Pedestal construction began with the pouring of 54,000,000 pounds of concreteâsaid to be the largest concrete foundation of its time. The concrete walls were designed to be up to 20 feet thick, with blocks of granite to finish the facade.
The pedestal stands 154 feet tall, making the top of the torch 305 feet above ground level. The statue contains 62,000 pounds of copper and 250,000 pounds of steel. The concrete pedestal weighs 54 million pounds. Winds of 50 miles per hour can cause the statue to sway up to 3 inches and the torch up to 6 inches.
