How much larger is a cube with a side length of

19
19 feet long than a cube of a side length of
11
11 feet long?

To find the difference in size between the two cubes, we can calculate the volume of each cube and then find the difference.

Volume of the cube with side length 19 feet:
\(19^3 = 6859\) cubic feet

Volume of the cube with side length 11 feet:
\(11^3 = 1331\) cubic feet

Difference in size:
\(6859 - 1331 = 5528\) cubic feet

Therefore, the cube with a side length of 19 feet is 5528 cubic feet larger than the cube with a side length of 11 feet.
