gmihir
let the sides be l,b,h we need unique v= lbh
now
statement 1:
any combination may give the result i.e. areas 10 and 25 no unique info
INSUFFICIENT
statement 2:
only one side known rest two are unknown
INSUFFICIENT
1) and 2):
one of the side is 5 ; other may be 2, 12.5
one is 5 other may be 5, 2
hence its not unique
INSUFFICIENT
Hence E
Hope this helps..!!

Statement 1: Areas of the two faces of the rectangular cuboid are 10 and 25. Only from this we can't determine the volume of the cuboid.
Not sufficient.
Statement 2: One of the dimension of the rectangular cuboid is 5 units. But we don't know about the other two dimensions.
Not sufficient.
1 & 2 Together: Different combinations are possible as any of the 3 dimensions (length, breadth, width) may be equal to 5 units. This will result in different volume.
Not sufficient.
