    The wall is square shaped.

    The dimension of wall is 5 feet by 5 feet.

    1 feet = 12 inches

    5 feet = 12*5 = 60 inches

    Area of square is given by:

    Area = side * side

    Area of square wall = 60*60 = 3600 square feet.

    Dimension of tile is 4 5/8 in. by 4 5/8 in.

    converting 4 5/8 into improper fraction (8*4+5) / 8 equals 37/8

    Area of one tile = (37/8) * (37/8) = 1369/64

    Number of tiles required can be found by dividing area of wall by area of one tile.

    Number of tiles = 3600 divided by (1369/64) = 168.298 = 168

    So number of tiles required will be 168.
