The Great Wall of China is about 20 feet high and about 15 feet wide. What is the volume of a 1-mile section of the wall?

To calculate the volume of a 1-mile section of the Great Wall of China, we first convert 1 mile to feet, which is 5,280 feet. The volume can be calculated using the formula for the volume of a rectangular prism: Volume = length × width × height. Therefore, the volume of a 1-mile section would be 5,280 feet × 15 feet × 20 feet, resulting in a volume of 1,584,000 cubic feet.
