Question

A square with an edge of exactly 1 cm has an area of:

Answer 1

s=1cm
area of square =
${s}^{2} \\ = {1 }^{2} \\ = 1 {cm}^{2}$

Answer 2

“A square with an edge of exactly 1 cm has an area of 10^-4 m^2.”

We are familiar that a square has 4 vertices, 4 edges, and 1 square face.

We can construct a model of a cube and count its 12 edges, 8 vertices, and 6 squares.

We are familiar that a four-dimensional hypercube has 16 vertices.
