Answer: 61 cubic meters
Step-by-step explanation:
The volume of a cube is given by :_
[tex]\text{V}=(s)^3[/tex], where s is the side-length of the cube.
The volume of cube with side-length 5 meters is given by :_
[tex]\text{V}=(5)^3=125\ m^3[/tex]
The volume of cube with side-length 4 meters is given by :_
[tex]\text{V}=(4)^3=64\ m^3[/tex]
The difference of the volumes of two cubes with side lengths of 5 meters and 4 meters :
[tex]125-64=61\ m^3[/tex]
