Answer
$A=2\times (2\times 6+2\times7+6\times7)=2\times 68=136$ square feet
$V=2\times 6\times7=84$ cubic feet.
Work Step by Step
This solid is a cuboid as all of its angles are right angles.
The volume of a cuboid can be calculated as:
$V=a\times b\times c$
Here:
$V=2\times 6\times7=84$ cubic feet.
The surface of a cuboid can be calulated as:
$A=2\times(a\times b+b\times c+a\times c)$
Here:
$A=2\times (2\times 6+2\times7+6\times7)=2\times 68=136$ square feet
