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..!!
