Let the edges of the bigger and smaller cubes be x cm and y cm, respectively.
Edge of the bigger cube, x = 12 cm
Edge of each smaller cube, y = 4 cm
∴ Number of smaller cubes that can be cut from the bigger cube
[Volume of cube = (Edge)3]
= 27
Thus, 27 smaller cubes of edge 4 cm that can be cut from a cube of edge 12 cm.
The number of cubes of edge 4 cm that can be cut from a cube of edge 12 cm, is ___27___.
