Cube (algebra) however, easy to show that most numbers are not perfect cubes because "all" perfect cubes must have digital root 1, 8 or 9. That is their values modulo 9 may be only −1, 1 and 0. Moreover, the digital root of any number's cube can be determined by the remainder the number gives when divided by 3: Every positive integer can be written as the sum of nine (or fewer) positive cubes. This upper limit of nine cubes cannot be reduced because, for example, 23 cannot be written as the sum of fewer than nine positive cubes: The equation has
The Cube (building) on top of the base, is a perfect cube element measuring in height, width and breadth. The cube consists of 16 floors, with retail distributed on the lower two storeys, office space on the above five floors, residential apartments on the above nine levels, with the top floor of the cube being shared with Hotel Indigo. The Cube residential apartments are separated into East and West Wing. East Wing is strictly limited to owner occupiers, according to contract it is not allowed to let. West Wing is buy-to-let, owner may occupy the flats or let to tenants. East and West
