Once Tom answered the question to unlock the car, he hopped in and drove off to reach his destination – a building calledTheArchitecture.This building closelyresembles a Rubik’s Cube, in the sense that the “rooms” of The Architectureare like the “cubes” of the Rubik’s Cube, as shown:
This building has 3 floors and each floor has 3 × 3 [read 3 by 3 – which means there are 3 rows and 3 columns] rooms which are all identical in size and shape.Tom stopped the car in front of the building.To enter this architecture, he should enterapasscodewhich is equal to the total number of rooms [cubes] in the building.
What is the passcode that Tom has to enter? ______ [Enter a numerical value]
Consider the base of The Architecture. It is given that there are 3 × 3 cubes [rooms] on each floor.
Since the building has 3 floors, the total number of cubes [rooms] would be 3 × 3 × 3 = 33 = 27.
