The Cube class contains two attributes: base$\_$area and side$\_$length. Cube object cube$1$ is created with the base$\_$area and side$\_$length attributes read from input. Given that $,$ use cube$1\text{'}$s attributes, base$\_$area and side$\_$length, to calculate total$\_$volume and assign the result to variable total$\_$volume.
