The ratio of areas is the square of the scale factor.
First, we find the scale factor from the blue solid to the red solid.
scale factor = 6/4 = 3/2
The ratio of areas is the square of the scale factor:
ratio of areas = (3/2)^2 = 9/4
volume of red solid = volume of blue solid * ratio of areas
volume of red solid = 336 m^2 * 9/4 = 756 m^2
Answer: S = 756 m^2
