Let’s say that
length—a,
width—b, and
height —c
Surface area of a certain rectangular solid — 2(ab+ac+bc)
Statement1:
ab=30
ac=45
Also, we need the value of ’bc’ to get the surface area of rectangular solid.
If a=5 and b=6, then c could be 9.
If a=3 and b=10, then c could be 15
Insufficient
Statement2:
abc=270
We could have the values of a, b and c:
—abc=5*6*9=270
—abc=3*10*9=270
Insufficient
Taken together,
abc=270
ab=30 —> c=9
ac=45 —>b=6
—> a=5
Now,
