This is a popular topic, discussed in many places on the web. The attached link is one place that I like. If you want to look for others just google for surface area square pyramid.
Surface area of the pyramid: 4*0.5*144*sin(60) = 249 square cm to 3 significant figures
The surface area of a square pyramid depends on the lengths of the sides of the square base and of the vertical height. While the question does give two linear measures, it does not say which is which! And without that crucial bit of information, I cannot provide a more useful answer.
There is not enough information to calculate the dimensions.
It is the lateral area (which is 1/2 the perimeter multiplied by the slant height), plus the area of the base.
total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides
If it is a 4 faced tetrahedron pyramid then its complete surface area is 4*80 =320 square centimetres
It depends on the dimensions of the base and the height (slant or vertical) of the pyramid.
The formula for a square pyramid is one square attached to four triangles which meet at a point.There are other formulae for the surface area or for the volume.
SA = s2 + 2 × s × l
