What is the formula for a triangular prism
A rectangular pyramid you use 1/3 or divide 3 in the product but a triangular prism you use 1/2 or divide 2 on the product.
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.
its not i dont no why
Length of prism * perimeter of triangular face.
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.
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.
What is the formula for a triangular prism
It depends on what information you have.
A triangular prism can be thought of as a stack of triangles. Then the volume is equal to the area of the triangular base multiplied by the height of the prism, or 1/2 length * width * height.
There must be a typo in this question, "Why does the formula for finding the surface area of arectangular prism is helpful?" What does that even mean?
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.
A rectangular pyramid you use 1/3 or divide 3 in the product but a triangular prism you use 1/2 or divide 2 on the product.
2*area of triangular base + perimeter of triangle*length of prism.
yes.
Whatever the net, the answer is the same area as that of the net.
