2*area of triangular faces + perimeter of triangle*length of prism (not prisim).
It is 288 cm^2.
The first comprises one rectangular face and four triangular faces whereas the second has two triangular and three rectangular faces.
Whatever the net, the answer is the same area as that of the net.
30cm
To find the surface area of an equilateral triangular prism you take the area of the rectangular sides and the triangular bases and add them up and your done.
Surface area of any pyramid is 1/2Pl + B; where P=perimeter of the base, l=slant height and B= Area of the base.
Well honey, to find the surface area of a triangular prism, you add the areas of all the individual faces. So, you calculate the area of the two triangular bases and the three rectangular sides, then add them all up. It's as simple as that, darling.
Surface area of the triangle x the length of the prism.
You find the area of the base and then find the area of one triangle. Multiply that one triangle by 4 and then add the base. The above is correct for a triangular pyramid NOT a triangilar prism. A triangular prism has two triangular ends and three rectangular faces. The rectangular faces need no be the same shape, but if they are, So Area = 2*area of triangular ends + 3*area of rectangular faces If not, you'll just have to calculate each area separately and add them.
bh+(S1+S2+S3)h
Surface = 2b + Ph (b is the area of the base P is the perimeter of the base)ORSurface Area= 1/2(B x h)(2) + (s1+s2+s3)hORSurface Area= (B x h) + (s1+s2+s3)hB= Base.H= Height.s1, s2, s3= Basically the perimeter of the base.Remember: the base of a triangular prism is not always on the bottom.
Capacity generally implies volume in geometry. To calculate the volume of a triangular prism, find the area of one of its triangular bases and multiply it by the height of the shape.
Like all prisms you find the area of one of the triangular faces and then multiply by the height.
okay, to find the base of a triangular prism you just b = 2a/h (base = 2 * area/height)
All you have to do is find the area divide it by the base and then you get the height.
PyramidV = 1/3 bhb is the area of the baseSurface Area: Add the area of the base to the sum of the areas of all of the triangular faces. The areas of the triangular faces will have different formulas for different shaped bases.
