OpenStudy (anonymous):

but i really have no idea

OpenStudy (anonymous):

i dont know how to find lateral area

jimthompson5910 (jim_thompson5910):

how did you find 448?

OpenStudy (anonymous):

2ab + 2bc + 2ac

jimthompson5910 (jim_thompson5910):

|dw:1400047931424:dw|

jimthompson5910 (jim_thompson5910):

The entire surface area is the sum of the areas of each face

jimthompson5910 (jim_thompson5910):

The lateral surface area is just the total area of the sides |dw:1400047987698:dw| so basically everything but the top and bottom
