Cube 1 has a volume of b3. the side lengths of cube 2 are twice those of cube 1. what is the volume of cube 2.a. b3d. (2b)3c. 2√bd. √2b

The volume of a cube is (also known as regular hexahedron) is equal to the length of its edges elevated to the cube (taking into account that in a cube each side and edge has the same size).

In this case we have a first cube (called cube 1) which edges are , hence its volume is:

Also we know cube 2  side lengths or edges are twice those of cube 1, this means:

Therefore the volume of cube 2 is:

Which is the same as:

Therefore the right answer is B
