    This is the concept of surface are of the solid materials;

    the dimensions of the foyer are:

    height = 9ft

    length=6.5 ft

    width=4.2 ft

    The surface area of Eric's foyer will be given by:

    Area=Area of the four walls+area of the ceiling

    Area = 2 (length*height) + 2 (width*height) + (length*width)

    Area=2 (9*6.5) + 2 (9*4.2) + (6.5*4.2)

    Area=2 (58.5) + 2 (37.8) + 27.3

    A=117+75.6+27.3

    A=219.9 ft^2

    The answer of the foyer is 219.9 ft^2
