Find a formula for the described function. an open rectangular box with volume 4 m3 has a square base. express the surface area sa of the box as a function of the length of a side of the base, x. sa = m2 state the domain of sa. (enter your answer in interval notation.)

Surface area = m².

And domain will be x∈ (0,∞)

Step-by-step explanation:

An open rectangular box with volume 4 m³ has a square base.

The length of a side of the base is x

We can say that

=>

Surface area can be found as:

Surface area = m².

And domain will be x∈ (0,∞) we can also say x>0

x is greater than zero as the surface area will always be a positive value and x cannot be negative.
