Question 136199: Three faces of a box have a common vertex and their combined area is 20cm^2. What is the total surface area of the box? Thank you Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Each of the 3 faces has an identical face opposite it, so
the total area is 20 vm2 + 20 cm2 = 40 cm2.
