    1.5 cm²

    Step-by-step explanation:

    Substitute a = 0.5 cm to the formula SA = 6a²:

    SA = 6 (0.5) ² = 6 (0.5 · 0.5) = 6 (0.25) = 1.5 cm²

    a = edge length = 0.5 cm

    S = surface area of cube

    S = 6*a^2

    S = 6 * (0.5) ^2

    S = 6*0.25

    S = 1.5

    The surface area of the cube is 1.5 square cm

    You can use cm^2 in place of "square cm" to mean the same thing.
