A large cube with an edge of 8 cm is made from the least possible number of centicubes. Although the
object looks solid, it is hollow inside. How many centicubes are needed to make the object?
+37157 If it were SOLID it would be made of 8 x 8 x 8 cubes = 512
to make a hollow shell you have to remove a 6 x 6 x 6 core = 216
512 - 216 = 296 cubes remain
