25. The ruins of The Parthenon in Athens, Greece is one of the most popular tourist destinations in all of Europe. Built in 447 BC during the Athenian Empire as a temple, The Parthenon’s structure can still be seen today. The outer perimeter of the temple (seen below) is lined with columns, common to Greek architecture during that time. Of the over thirty columns that surround the temple, most are up to 6 feet in diameter and 34 feet tall. The mixture needed to make the columns was a limestone/marble mined from a quarry over 20 miles away so the volume of each column was calculated before construction. The Greco-Roman architecture of The Parthenon and its world renowned columns have stood the test of time with thousands of visitors touring the ancient temple each year.
With each column having a radius of around three feet and a height of 34 feet, what is the approximate volume in cubic feet of each one of The Parthenon’s famous columns?
a. 961.3 fb. 640.9 f
b. 320.4 fd. 2,142.2 f
