Surface area of the triangle x the length of the prism.

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.

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.

2*area of triangular base + perimeter of triangle*length of prism.

To calculate the surface area of the equilateral triangular-based prism, you need to calculate the area of the equilateral triangle and all the other sides of the prism. The total area of all the phases will give the total surface are of an equilateral triangular based prism.

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.

2*area of triangular faces + perimeter of triangle*length of prism (not prisim).

Whatever the net, the answer is the same area as that of the net.

Area of triangle * 2 + perimeter of triangle * length.

The two nets of a regular right triangular prism are surface area and volume.

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.

A triangular prism is a three-sided prism with three faces joining corresponding sides. The formula for its surface area is SA = wh + lw + lh + ls, where l=length, h=height, w=width and s=side.

No the area is when you are dealing with a 2-dimensional figure. Surface area formulas vary depending on if the object is a rectangular prism, a pyramid, a cone, or a triangular prism. a.k.a. the object needs to be 3-D to have a surface area.

It is important to remember the formulas when learn Geometry. The surface area formula for a triangular prism is A=2A(subscript B)+(a+b+c)h.

Work out the area of each of the 5 nets and then add them together

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.
