This is from Tools 4 NC Teachers. This task provides the opportunity to engage in a rigorous task about volume with very large numbers. The multiplication and operations of the numbers align with the Grade 5 Standard, but the work with volume with such large numbers goes beyond the Standard. This is remixable.

This is a diagram (pictured when you download the file) of the Sears Tower (now called the Willis Tower) skyscraper in Chicago.  

*Note the range of numbers in this problem are beyond the one-digit dimensions in the standard.

The base of the tower is a 75 x 75 meter square.   If each floor is 4 meters tall, what is the volume of the Sears Tower?
