Terrance needs to find the lateral surface area of the box shown below. Assuming the base is the bottom of the prism, which of the expressions below will give him the correct lateral surface area?
length:14.5
width:7
height:8.6
(14.5 +14.5 + 7 + 7)(8.6)
(14.5 + 7)(8.6)
(14.5 +14.5 + 7 + 7)(8.6) + 2(14.5)(7)
The correct expression is:
(14.5 + 7)(8.6)
