Yahoo! will not allow diagrams to be posted here. Words will have to do.
Let there be a cuboid of edges 2, 4 and 8 units
Volume = 2*4*8 = 64 cubic units
Take a cube of side 4 units
Volume = 4^3 = 64 cubic units
SA of cuboid = 2(8 + 32 + 16)
= 2 * 56 sq. units
= 112 sq. units
SA of cube = 6 * (4)^2
= 6 * 16
= 96 sq. units
The volumes are same, but surface areas are different

Sure,
A rectangular prism with sides 4, 4, and 3 has volume 48 and SA 80
A pyramid with base 4x4 and height 9 has volume 48 and surface area 89.75
