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.
It is not complicated to derive the formula of the surface area of a square pyramid. Start with a square pyramid as shown below and call the length of the base s and the height of one triangle l. l is the slant height. It is not for no reason this height is called slant height! The word slant refers also to something that is oblique or bent, or something that is not vertical or straight up. Basically, anything that is not horizontal or vertical! The area of the square is s 2. The area of one triangle is (s Ã l)/2. Since there are 4 triangles, the area is 4 Ã (s Ã l)/2 = 2 Ã s Ã l.
