Cube and rectangular prism
A cube is a three-dimensional solid with 6 sides whose length, width, and height are equal. Its angles are right.
To calculate the volume and surface area, use these formulae:
$$V=a×a×a=a^3$$
$$S=2a×a+2a×a+2a×a=6a^2$$
A rectangular prism is a three-dimensional solid which has six faces that are rectangles. Its angles are right.
$$V=a×b×c$$
$$S=2a×b+2b×c+2a×c$$
