    96 in²

    Step-by-step explanation:

    for a cube of side 4 inches

    area of each face = 4 x 4 = 16 in²

    However we know that a cube has 6 identical faces,

    Hence surface area of cube

    = 6 x area of each face

    = 6 x 16 in²

    = 96 in²

    96 inches squared

    Step-by-step explanation:

    One side is equal to 4 in

    All cube sides are the same

    á = s^2

    s = 4

    a = 4^2

    a = 16 square inches = 1 side

    Cube has 6 sides

    6 (16) = 96 inches squared = Surface area
