The ratio of the side lengths is 4:6 or 2:3.

Since the figures are similar, the ratio of areas is 2^2:3^2 = 4:9

You can do the arithmetic.

It's a basic principle about similar figures -- the ratio of areas is the square of the ratio of linear measurements (scale factor); the ratio of volumes is the cube of the scale factor.
