V = (4)(7)(12) = 336 cm^3

SA = 2(4 * 7 + 4 * 12 + 7 * 12) = 320 cm^2

the volume is the 3 sidelengths multiplied together, so:

$V=4\cdot12\cdot7=\boxed{336}$cm$^3$

surface area is each side length times the other multiplied by two:

$SA=2\cdot(4\cdot12+4\cdot7+12\cdot7+7\cdot4)=2\cdot(160)=\boxed{320}$cm$^2$
