```How about this:

Graphics3D[{Red, Opacity[1],
Polygon[{{0, 0, 0}, {1, 0, 0}, {1, 1, 0}, {0, 1, 0}, {0, 0, 0}}],
Opacity[0.9],
Polygon[{{0, 0, 0}, {1, 0, 0}, {1, 0, 1}, {0, 0, 1}, {0, 0, 0}}],
Polygon[{{0, 0, 1}, {1, 0, 1}, {1, 1, 1}, {0, 1, 1}, {0, 0, 1}}],
Polygon[{{0, 1, 0}, {1, 1, 0}, {1, 1, 1}, {0, 1, 1}, {0, 1, 0}}],
Polygon[{{0, 0, 0}, {0, 1, 0}, {0, 1, 1}, {0, 0, 1}, {0, 0, 0}}]}]

You can play with the Opacity, but even with both set at 1.0, the front
looks open.
