Best Answer

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.

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

47.88 cm2

Assuming you mean a rectangular prism, you get the smallest surface area if the prism is a cube. You can calculate the required length of side to get that volume; then, based on that, the corresponding surface area.

The triangular prism has the two triangular bases and rectangular side faces.

Multiply the length of the prism by the area of the triangular face. How you find the area of the triangular face will depend on what information you have about the triangle: 3 sides, 2 sides and the included angle, 1 side and 2 angles, base and vertical height or any of a number of other sets of data.

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.

You must be thinking of a triangular prism. In that case, c is the length of the third side of the triangle at the end of the prism.

you would have to add all the different areas of each side together to get the surface area. the formula though, would be side area times three, plus the base

Surface Area= Base x Height+(Side 1+ Side 2+ Side3 ) x Height SA=bh(s1=+s2+s3)h

I believe the answer is 240 square inches.

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))).

You can think of a square prism as a die, having six sides. So you need the length of one side, 's'. That side's [surface] area is s2 With six sides, the cube's surface area is simply: 6s2

Rectangular Prism surface area formula is Area = 2 (wh + lw + lh) (Length x width of a side) x 2 + (length x width of perpendicular side) x 2 + (length x width of end) x 2 = surface area of a rectangular prism
