    What is the ratio of the area of the shaded cross-section to the area of one of the square faces of the cube? 1 : 1 2√:1 3√:1 2 : 1

    let's ignore the height for a sec, look at the base, we can find the length of the hypotenuse by using our pythagorean theorem, ya? :)

    So we've got uhhh,, \(\Large\rm a^2+a^2=c^2\) where c is the hypotenuse, ya? Solve for that length c.

    |dw:1432784993245:dw|The area of the diagonal wall that was cut is given by width times the height, so that hypotenuse length times the height a. \(\Large\rm c\cdot a\) And the area of any face is going to be \(\Large\rm a\cdot a\) So the ration is ca:aa or to simplify things lets call the side lengths 1 as the gal was suggesting earlier :) c:1 So find that hypotenuse length!
