Answer:
360 mm^2
Step-by-step explanation:
To solve this problem we will need to set up an equation as follows.
SA = (2w)(2w)+2(2w)(s)
We already know the width so the only thing we need to find is the slant height. To do this, we use the Pythagorean Theorem, substituting w as a, h as b, and s as c. w^2+h^2=s^2
Simplifying we get 13 and we just plug in the numbers into our formula to solve.
