What is the formula for finding surface area of a triangular prism?
Next, multiply the base times height for the area of the triangles (bh), and add their three sides (s1 + s2 + s3).
Then, multiply the sum of the triangle sides by the height of the prism (H) and add the values together for the answer, remembering to include the appropriate unit of measurement.
How do you find the surface area of prisms?
To find the surface area of a prism (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. To find the volume of a prism (it doesn’t matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h.
What is the formula for a right triangular prism?
To calculate the volume of a triangular prism, measure the width and height of a triangular base, then multiply the base by the height by 1/2 to determine the triangle’s area. Next, measure the height of the triangular prism and multiply this by the triangle’s area to get the volume.
How do you find the surface area of a triangular pyramid?
To find the surface area of a regular triangular pyramid, we use the formula SA = A + (3/2)bh, where A = the area of the pyramid’s base, b = the base of one of the faces, and h = height of one of the faces.
