**drwls**, Friday, September 5, 2008 at 12:28amThe base area equals six times the area of an equilateral triangle with side length 20 cm (since six equilateral triangles make up a hexagon). Multiply that area by the base edge height for the volume.

Add twice the base area to the area of the six 20x16 cm faces to get the area.

hint: equilateral triangle area =

(1/2)*(side length)^2*[sqrt3)/2]
