    Answer:  Approximately 96 square feet

    ======================================================

    Work Shown:

    1 ft = 30 cm

    1 ft = (5*6) cm

    1 ft = 5*(6 cm)

    1 ft = 5*(1 board width)

    1 ft = 5 board widths

    12*(1 ft) = 12*(5 board widths)

    12 ft = 60 board widths

    12 ft = 1 full wall length

    The wall is 12 feet horizontally across and 8 feet tall, so its estimated area is 12*8 = 96 square feet approximately. This is approximate because of the fact we used the approximation of 1 ft = 30 cm.
