Answer: The length, breadth, and height of the given object are 3x+y cm, 2x+2y cm, and 3y cm, respectively. To find the volume of this object, we need to multiply these three dimensions:
Volume = Length x Breadth x Height
= (3x+y) x (2x+2y) x (3y)
= 18x^2y + 27xy^2 + 6xy^2 + 6y^3
= 18x^2y + 33xy^2 + 6y^3
Therefore, the volume of the object is 18x^2y + 33xy^2 + 6y^3 cubic cm.
