The volume of a regular pyramid is 1/3*area of the base*hight
The formula to find the area of an octagonal pyramid is area of base plus area of sides.
Figure it out stupid.
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
Use the formula 1/2bh to find the area of a triangle side. Then multiply that by 6 because you have 6 sides on the base.
you dont
The surface area of a pyramid is the area of all the faces of the pyramid, for a pyramid with apex in the centre and a regular polygon as its base, (the bottom of a pyramid is the base, it is regular if all sides are the same length) the surface area is: B + 1/2(P * H) where B is the area of the base, P is the perimeter (area around) the base and H is the height of the pyramid.
It is 288 cm^2.
The answer depends on what information you do have about the pyramid.

There is no "regular pyramid". There are triangle pyramids, square pyramids, pentagon pyramids, etc. With the information given in your question, there is no way to answer.
the question is the anwser
Surface Area= 1/2perimeter x slant height + B * * * * * Perimeter = perimeter of base. B = Area of base.
It is not possible to answer the question without knowing if the pyramid is a triangle based, square based or other polygon based pyramid.
It is not possible to answer the question because the shape of the base is not known. As a result the surface area of the base, and hence the total surface area cannot be calculated.
A regular polygon has equal sides and angles. A polygon has a surface area but a polyhedron has many faces as for example a pyramid.
