    The cube has 6 equal, square, foil faces. The mass of foil for each face is (380/6) milligrams.

    The surface area of each piece is (380) / (6•11) cm^2.

    The length of each side of the piece is √ (380/6•11) cm

    That's about 2.4 cm.

    It's a cute little foil cube, just under 1-inch each way.
