Surface area of two cubes = 6 times [ (length of first cube's edge)2 + (length of second cube's edge)2 ]
To create a cube with an edge length of 7 inches, you need to calculate the volume of the cube. The volume is found by cubing the edge length: (7 \times 7 \times 7 = 343) cubic inches. Therefore, you would need 343 one-inch cubes to fill the larger cube.
To create a cube with an edge length of 6 inches, you need to calculate its volume. The volume of a cube is found using the formula ( V = s^3 ), where ( s ) is the length of an edge. So, ( V = 6^3 = 216 ) cubic inches. Therefore, you need 216 one-inch cubes to create a cube with an edge length of 6 inches.

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.
