Answer
$V=72$ cubic in.
$A=108$ square in.
Work Step by Step
The volume of a rectangular cuboid can be calculated as:
$V=a\times b\times c$
Here:
$V=6\times4\times3=72$ cubic in.
The surface area of a rectangular cuboid can be calculated as:
$A=2\times(ab+ac+bc)$
Here:
$A=2\times (6\times4+6\times3+4\times3)=2\times(24+18+12)=2\times54=108$ square in.
