Apiece of aluminum foil has a known surface density of 11 mg/cm2. if a 380 milligram hollow cube were constructed using this foil, determine the approximate side length of this cube.

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.

c) power lifting, will be your answer.
