$A=2\times (2\times 6+2\times7+6\times7)=2\times 68=136$ square feet $V=2\times 6\times7=84$ cubic feet.
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
