Three cube-shaped boxes are stacked one above the other. the volumes of two of the boxes are 1,331 cubic meters each, and the volume of the third box is 729 cubic meters. what is the height of the stacked boxes in meters?

Long (cube)=widh (cube)=height (cube)=S (side)

volumue of a cube=side³ ⇒  side=∛volume of a cube.

first box and second box:

side=∛1331 m³=11m

Third box:

side=∛729 m³=9 m.

answer : the height of the first and second box is 11 m, and the height of the third box is 11 m.
