<PRE><B>Question 92381</B>
the total area of six faces of a cube is 240 cm^2 how long to the nearest 10th is one egde
--------
The area of one face must be 240/6 = 40 cm^2
-----------
Since each face is a square and since the area of a square is (side)^2
you get:
EQUATION:
(side)^2 = 40
side = 2sqrt10 cm
