Answer:
648 cm Cube
Explanation:
Here total volume comprises of volume of the cube and the volume of cuboid.
Let the volume of Cube be
and Volume of Cuboid is
Hence total volume

Let evaluate both of them one by one.

Where side = 6
Hence



Length = 12 ; breadth = 6 and height = 6
Hence


Hence


Therefore volume of the solid space is 648 cubic cm
