Each dimension of a certain rectangular solid is an integer less than 10. If the volume of the rectangular solid is 24 and one edge has length 4, which of the following could be the total surface area of the solid?

A. 48
B. 52
C. 56
D. 60
E. 96



4*x*y=24
x*y=6
so x*y can be 1*6 or 2*3

2*(lb*bh*hl)

2*(6+8+12)
2*26 = 52 IMO B
