**drwls**, Saturday, May 21, 2011 at 9:58amThe area of a rhombus is 1/2 the product of the diagonals.

The top and bottom of your prism are rhombuses with areas of 60 sqrt3 ft^2, EACH.

The four rectangular sides of the prism each have areas of

(height)*[(a/2)^2 + (b/2)^2]

where a and b are the rhombus diagonal lengths. The term in brackets is the rhombus side length, and equals 12 feet in this case.
