  • math models -

    1 ft = 12 in

    1 ft ^ 2 = 12 ^ 2 = 144 in ^ 2

    Areaa od a kitchen

    Ak = 20 * 16 = 320 ft ^ 2

    Ak = 320 ft ^ 2 = 320 * 144 = 46,080 in ^ 2


    Area of tiles

    At = 6 * 6 = 36 in ^ 2


    Numbers of a tiles

    n = Ak / At

    n = 46,080 / 36 = 1280


    OR


    20 ft = 20 * 12 = 240 in

    One side of tiles = 6 in

    240 / 6 = 40


    16 ft = 16 * 12 = 192 in

    One side of tiles = 6 in

    192 / 6 = 32


    n = 40 * 24 = 1280
