What is the volume of the cube above?

(1) The surface area of the cube is 600 square inches.

(2) The length of diagonal AB is 103 inches.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

求NN指点解题思路。cute是指正立方体吗?

cube是立方体的意思!

我知道条件(1)单独肯定充分,可是大家能不能给我解释一下,怎么样用条件(2)的出答案呢?

感谢了~~

由于没看到图,个人猜测AB应该是此正方体的对角线.则AB和任意1面的对角线,及一个边组成1个直角3角形,AB=边长的根号3倍,也可以求的体积.
