A. 60
B. 120
C. 450
D. 1,800
E. 3,600



OA B
let the sides of the rectangular solid are a,b and c.
given,ab=12,bc=15 and ca=20

ab*bc*ca=12*15*20
(abc)^2=3600
abc=60, the volume of the solid.

That's right, Krazzy.... I get the same answer. It's a pretty simple problem so i don't see 2 ways about it.
I think the OA of B is a typo. Pls confirm
