Surface area of two cubes = 6 times [ (length of first cube's edge)2 + (length of second cube's edge)2 ]
If many smaller cubes are combined to form a larger cube, then the surface area of the large cube is: 6 x (length of one side squared)
no
The volume of a cube is the length of the side, cubed.The area of a cube is 6 times (the length of a side squared).
When a solid wooden cube is painted blue and then cut into 27 smaller cubes, the original cube's surface area is divided among the smaller cubes. Since each side of the larger cube is painted, the outer layer of the smaller cubes will be blue. Out of the 27 smaller cubes, only the 8 cubes in the center do not have any blue paint, while the remaining 19 have at least one face painted blue. Therefore, the fraction of the total surface area that is blue is ( \frac{19}{27} ).
Congruent ones. A cube of side x has a volume of x3. Any other cube, of volume x3 must have sides of length x and so the two cubes must be congruent.
Yes, a cube has six faces. They also happen to congruent because all the side lengths in a cubes are congruent.

All six sides of a cube are congruent. One of the definitions of a cube is "all congruent sides."
(surface area of cube 1 or 2 (either)) times 2 = (total surface area of two identical cubes)
Assuming that the cubes are 1x1x1, there will be one thousand cubes in the larger cube.
