There are 64 such cubes.
Edge of the larger cube = 32 cm Volume of the larger cube = (32 cm)3 = 32768 cm3 Edge of the smaller cube = 4 cm Volume of the smaller cube = (4 cm)3 = 64 cm3 Since the smaller cubes are cut from the larger cube, volume of all of them will be equal to that of the larger cube. ∴ Total number of smaller cubes × Volume of the smaller cube = Volume of the larger cube ⇒ Total number of smaller cubes = Volume of the larger cube ÷ Volume of the smaller cube ⇒ Total number of smaller cubes = 32768 ÷ 64 = 512 Thus, 512 smaller cubes can be cut from the larger one.

2 x 2 x 2 = 8 cubes.
Volume of 1 cm cube = 1 cubic cm (cc) Volume of 4 cm cube = 4*4*4 = 64 cc So number of unit cubes required = 64
You would need 8 smaller cubes with 2 cm edge to form a larger cube with a 4 cm edge.

Surface area of two cubes = 6 times [ (length of first cube's edge)2 + (length of second cube's edge)2 ]
There are 64 such cubes.
