Question

Hi all! I have a question :) "An open rectangular box with volume 2m^3 has a square base. Express the surface area of the box as a function of the length of a side of the base"

Answer 1

:/

Answer 2

Area of base is x^2
Volume = base * height
2 = x^2 * h
h = 2/ x^2

4(2 / x^2)(x) + x^2 = SA
SA = 8/x + x^2

Answer 3

how do you figure out the height? That was my problem
