The surface area of a cube is 6 times e^2, where e is the length of each edge (that is, the surface area is the number of faces times the area of each face). Apply this formula to Quantity A:
A=6^3
The volume of a cube is e^3, where e is the length of each edge. Apply this formula to Quantity B:
B=6^3
It is not generally the case that the volume of a cube in cubic units is equal to the surface area of the cube in square inches; they are only equal when the edge of the cube is of length 6. In this case, the two quantities are equal.
