i got no idea i looked up this question and it took me her so idk

Divide by the number of faces. For example, divide by 6 if it is a cube. Divide by 4 if it is a triangular pyramid.

The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.

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.

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.

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.

to find the surface area you have to first find the area of each part then add the areas together.

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.

Find the surface area of each of the four triangular faces (they need not be the same) and sum the individual areas.

you calculate the area of one side, then multiply it by three.

It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.

The surface area of a rectangular prism is the sum of the length times the width of its three pairs of faces. A triangular wedge is half of that.

You have to find the areas of each individual triangle's area and add them all up together.

Rectangular Prisim 2x(area of front)+2x(area of side)+x2(area of length) Cube 2x(area of side)+2x(area of side)+2x(area of side)
