What is the difference between total surface area and lateral surface area?
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
What is the formula for finding the surface area of a triangular prism?
find the area of all the faces then add them all up. this is how you get surface area and there isn't any formula for it
How do you work out the surface area for a triangular prism?
To work out the area of the rectangular faces, you need to multiply the length by the width. You then need to multiply that answer by 3 (because there are 3 rectangular faces).To work out the area of the triangular faces, multiply the base of the triangle by the height and divide the answer by 2 (to find the area of one triangle). You then need to multiply it by 2 again because there are 2 triangular faces.Important: The height of a triangle is the distance from the top corner of the triangle down to the base (so that it meets the base at 90 degrees)You then need to add the total surface area of the rectangular faces to the surface area of the triangular faces to get the total surface area of the entire prism.(sorry for the essay :])
What is the surface area and volume of a triangular-based pyramid?
Volume_any_pyramid = 1/3 × area_base × perpendicular_height For a triangular pyramid (tetrahedron) this becomes: volume = 1/6 × base_width × base_height × pyramid_height For the surface area there is no (easy) general formula: the area of the base triangle and the area of the three side triangles need to be worked out and added together.
Formula for surface area of a triangular prism?
A triangular prism is a three-sided prism with three faces joining corresponding sides. The formula for its surface area is SA = wh + lw + lh + ls, where l=length, h=height, w=width and s=side.
Find the surface area of the right triangular prism?
the defnition of find the surface area of triangular prism and cylinder
How do you find the surface area of an equilateral triangular prism?

How do you find surface area of a triangular prisim?
2*area of triangular faces + perimeter of triangle*length of prism (not prisim).
Is the surface area of a triangular prism cubed?
Surface area is squared; volume is cubed.
Can you divide the surface area of a cube in half to get the surface area of a triangular prism?
Yes it is possible.
Is there a essayer why to do surface area of triangular prism?
A surface area would be vital for determining volume
How do you find the surface area of a triangular surface?
to find the surface area you have to first find the area of each part then add the areas together.
What is the formula for finding the total surface area of a triangular prism?
Assume that a = apothem length of the triangular prism, b = base length of the triangular prism, and h = height of the triangular prism. The formulas to find the surface area is SA = ab + 3bh.
