In Elena's favorite video game, players stack blocks to create buildings. Elena builds a fort shaped like a cube. Elena's fort has a length, width, and height of 9 meters. What is the volume of Elena's fort?

The volume of Elena's fort is:

9 meters (length) x 9 meters (width) x 9 meters (height) = 729 cubic meters

To find the volume of Elena's fort, we need to multiply its length, width, and height.

Given:
Length = 9 meters
Width = 9 meters
Height = 9 meters

To calculate the volume:
Volume = Length x Width x Height

Substituting the values:
Volume = 9 meters x 9 meters x 9 meters

Simplifying:
Volume = 729 cubic meters

Therefore, the volume of Elena's fort is 729 cubic meters.
