The question makes no sense. What on earth is a 18 foot square cube? Is it a cube each of whose faces is 18 square feet? Is it a cube each of whose edges is 18 feet - in which case why is the word "square" present?

A perfect Square means a shape having 4 equal sides and the angle between two adjecent lines should be 90, But a perfect Cube means its an OBJECT with its four sides are equal dimentions. Any square has 4 equal sides and 90 degree corner angles. This is a question about number theory. A perfect square is a number whose square root is an integer (eg 9, 49 etc). Similarly a perfect cube is a number whose cube root is an integer (eg 8, 27 etc)
No. A square is a 2-dimensional figure. A cube is a 3-dimensional figure whose faces are all squares.
