standard_description: Write an inequality of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.
problem_activity: A cube has
$$6$$
equal sides, each with an area of
$${s^2}$$
square units. The surface area of a cube is the total area of all six sides, and is represented by the formula
$$S=6{s^2}$$
.
Find the surface area of a cube with the side lengths below.
a.
$${s=3}$$
inches
b.
$${s=1.2}$$
cm
c.
$${s={2\over3}}$$
ft
