Dungeness Crabs go down well on their own. If you serve them as a main dish, serve them with lemon wedges and make sure you have a cracker or kitchen shears ready to open up the legs. This particular species of crab also is an abundant source of important minerals including copper, calcium, iron, zinc and magnesium.
Surface area of Rectangular pyramid (SA) = lb + l s1 + b s2. 'l' is length, 'b' is width. s1 is the slant length of the triangles with base 'l'. s2 is the slant length of the triangles with base 'b'. Example: Find the surface area of a rectangular based pyramid whose base is 12x8 m and slant heights are 10m and 12 m.
The formula used to calculate surface area for the classic square pyramid is: SA = [2 * b * h] + b^2. 1  SA and l represent the same values as before. 2  The abbreviation b represents the base length of the pyramid. 3  Note that [2 * b * h] is used to calculate the lateral area of the square pyramid.
