Interpretation: Whether the cube at the right side is pure aluminum or not needs to be determined.
Concept introduction: 3-dimensional structure (square) with 6 equal sides is identified as a cube. An element that effortlessly forms positive (+ve) ions (or cations) is defined as a metal. Metals have metallic bonds.

Answer to Problem 1PP
No, the cube pictured at right is not made of pure aluminum.
Explanation of Solution
The given cube is as follows:
Aluminum is usually listed in the class of metal. The color of aluminum is silvery-white and also, it is a light weight metal.
Pure aluminum is ductile, soft, corrosion-resistant. It has a quality of high electrical conductivity. The density of the cube (pictured) is not equal to the density of pure aluminum (it is
