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.
Hexagonal prisms cannot be regular. If you tried to make one it would end up being a hexagon since six equilateral triangles make a hexagon. Therefore, there is no surface area.
The surface area of a hexagon is the same as its area. You will normally need to split the hexagon into triangles, find their area and sum these.
you calculate the area of one side, then multiply it by three.
Find the areas of the rectangles and triangles. Add them together.
find the area of triangles(reflecting surfaces) and also the area of rectangle or square(base)and find the sum of both.
A=1/2bh The area of a triangle is 1/2bh. If the base of it is a triangle and all 4 of the triangles aren't the same, then you have to find the area of the base triangle and then the three other triangles (which should all have the same area). If all four of the triangles have the same area, then just find the area of one of the triangles and multiply that by four. A triangular pyramid that has four equal triangles is also called a tetrahedron.
If its a triangular based pyramid (tetrahedron) then it will have 4 equilateral triangle faces and so find the area of one face and multiply it by 4 to give the total surface area.
If a triangle is isosceles, then it is equilateral. To find the converse of a conditional, you switch the antecedent ("If ____ ...") and consequent ("... then ____."). (Of course, if not ALL isosceles triangles were equilateral, then the converse would be false.)
Obviously homework, so I'll give you some pointers:Assuming it is a regular hexagon then:Draw in all three diagonals of the hexagon - this will split the hexagon into 6 equilateral triangles.Sum the areas of the triangles to give the area of the hexagon.Use Pythagoras or trigonometric ratios to find the altitude of the triangles; the base of the triangles is the length of the side of the hexagon.
To find the surface area, the surface area of each rectangular side and the surface areas of the two triangular ends must be calculated. Given an equilateral triangular prism of height X and sides Y, each side has a surface area of X * Y. The end triangles are solved by using the Pythagorean theorem (a^2 + b^2 = c^2). In this case, a and c are known as Y and Y/2, so b= square root (Y^2 - (Y/2)^2). The area of a triangle is 1/2(base * height), where the base is Y and the height is b. The total surface area is then 3 * (X * Y) + 2 * ( 1/2 * (Y * (Y^2 - (Y/2)^2))).
A triangular prism has 5 sides. Three are rectangles and two are triangles. If you fold the net out flat you can get the dimensions and find the surface area. Each rectangle is length by width. And the triangles should be congruent and remember are length times height divided by two.
