Question 1020374
.
The surface area of a cube is 78 in.² what is the lateral surface area? 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


The lateral surface area is {{{(78/6)*4}}} = 13*4 = 52 {{{in^2}}}.


We divide the total surface area (78 {{{in^2}}} by 6 to get the area of one of the six faces, 
and then multiply by 4 to account for four lateral faces.
