Eight cubes, each with a volume of 512 cm^3, are joined to form one large cube. What is the surface area of the large cube?	Choose the correct choice from the following:	A) 4096 sq cm	B) 1536 sq cm	C) 1024 sq cm	D) 2048 sq cm	E) 512 sq cm

Rationale: volume = a x a x a = a ^ 3 volume of cube = 8 x 512 = 4096 cm ^ 3 4096 = a ^ 3 a = 16 surface area of cube = 6 a ^ 2 = 6 x 16 ^ 2 = 1536 answer is b
Answer: B
