**drwls**, Saturday, May 21, 2011 at 9:46amThe length of the base (b) of each triangular side is sqrt 121 = 11 mm. The height (h) of each triangle is the 18 mm slant height. Therefore each of the four sides has an area of

1/2 (base)*(height) = 11*18/2 = 99 mm^2

The total lateral area is therefore 4*99 = 396 mm^2
