All you have to do is find the area divide it by the base and then you get the height.
The area of a triangular roof section with a base of 7 feet and a height of 3.5 feet is
(1/3) * (base area) * height
When you say surface of a prism this means the total amount of space on the outside of the prism. You have specified it to be a triangular prism, but taking the surface area of all prisms is the same process for all prisms. When finding the surface area of a prism you always use this equation... S.A. = (2 x Area of Prism Base) + (Height x Perimeter of Prism Base) In a triangular prism the base would be a triangle. Therefore to find the area you have to do 0.5 x base of the triangle x height of the triangle. For the perimeter of the triangle just add the length of all the sides together. The height indicated in your S.A. = ... formula... is how tall the prism actually stands. So since this prism is a triangular prism take the general surface area equation and put the correct triangular measurements into the general equation and you have this... S.A. = [2 x 0.5 x (height) x (base)] + [Height x perimeter] Here is the formula in word form. The surface area of a triangular prism is equal to two multiplied by one half multiplied by the height of the traingular height multiplied by the triangular base compute this number and then add it to the product of the height of the prism times the perimeter of the triangular base.
Surface area of a triangular pyramid: SA = 1/2 as + 3/2 sl a = altitude of the base triangle s = side of the triangle l = slant height of the pyramid.
triangular prism- formula: Abh(area of the base * height)
Area = (base x height) / 2
All you have to do is find the area divide it by the base and then you get the height.
Like all prisms you find the area of one of the triangular faces and then multiply by the height.
Volume = 1/3 * Base area * Height So Base area = 3 * Volume / Height
The area of a triangular roof section with a base of 7 feet and a height of 3.5 feet is
A triangular prism can be thought of as a stack of triangles. Then the volume is equal to the area of the triangular base multiplied by the height of the prism, or 1/2 length * width * height.
It is impossible to find the area of a triangle with no height, if the triangle had no height it would not even be a triangle, just a angle.
To find the volume of a triangular prism, find the area of one of the triangles (base of the prism) first (base x height divided by 2). When you have the area of the triangle, then multiply the area of the triangle by the height of the prism, *not the height of the base.
(1/3) * (base area) * height
V = base area × height
It is 1/2*base*height of the triangle.
