Can a certain rectangular sheet of glass be positioned on a rectangular tabletop so that it covers the entire tabletop and its edges are parallel to the edges of the tabletop?

(1)     The tabletop is 36 inches wide by 60 inches long.

(2)     The area of one side of the sheet of glass is 2,400 square 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.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

我觉得题目问能否，只要是能就应该是选C啊，讨论利说得什么80×30只是否得情况，他是完全可以得

就是说如果玻璃是80X30的，那么是没法盖住桌面的，如果是60X40的，那么就是可以盖住桌面的，所以答案不唯一
