Answer:

Step-by-step explanation:
Given a box with a square base and an open top which must have a volume of 237276 cubic centimetre. We want to find a formula for the surface area of the box in terms of only x, the length of one side of the square base.
Let the side length of the base =x
Let the height of the box =h
Since the box has a square base
Volume,

Surface Area of the box = Base Area + Area of 4 sides

Substitute h derived above into A(x,h)

Therefore, a formula for the surface area of the box in terms of only x, the length of one side of the square base is:
