Answer:
If the ratio of the volumes is 3, then the ratio of the linear dimensions is the cube root of 3, or about 1.44224957, and the ratio of the areas is the square of that, or about 1.2. Then the area of B’s label is 75 * 1.2, which is about 90. You can get the 1.2 ratio by typing “square of the cube root of 3
