Answer
$128$ cubic cm.
$160$ square cm.
Work Step by Step
The volume of a rectangular cuboid can be calculated as:
$V=a\times b\times c$
Here:
$V=4\times4\times8=128$ cubic cm.
The surface area of a rectangular cuboid can be calculated as:
$A=2\times(ab+ac+bc)$
Here:
$A=2\times (4\times4+4\times8+4\times8)=2\times(16+32+32)=2\times80=160$ square cm.
