Best ResponseYou've already chosen the best response.0Well, the surface area is 2*(lb+bh+lh) where l=net length, b=neet breadth, h= net height Here, total length= 4*4 =16unit (since four cubes side to side, each with length 4 unit) breadth= 2* 4=8unit (since 2 cubes top to bottom) h=4unit (1 cube) So the surface area is: 2*(16*8+8*4+16*4)
