if a 6 cm cube is cut into 1 cm cubes , then what is the percentage increase in the surface area of the resulting cubes ?
"the area a of the large cube is 6 * 6 * 6 = 216 square cm . the area of the 216 small cubes is 216 * 6 = 6 a , an increase of 500 % . the answer is c ."
multiply(const_100, divide(multiply(surface_cube(1), surface_cube(6)), surface_cube(6)))
