surface area? b/c that's the area of a 3-d object. But there is also volume.
SA=find the area of each face and add them together(1/2 base times height for triangles and B times H for rectangels)
V= the area of the base times the height
8cm 6cm 7cm 3cm
The Surface area of a triangle = 0.5*base*height The volume of a prism = area of its cross-section*length
It is the perimeter of a triangle times the length of the prism (in square units).
Area of triangle * 2 + perimeter of triangle * length.
The area of the cross section (the triangle) muliplied by the length of the prism. Area of triangle= 0.5 x base x height Then mulitply by the length the prism goes back
You can't.
To find the volume of a triangular prism, find the area of one of the triangles (base of the prism) first (base x height divided by 2). When you have the area of the triangle, then multiply the area of the triangle by the height of the prism, *not the height of the base.
The formula is Bxh where B is the base which is the area of the triangle and h is the height of the prism.
To calculate the volume of a right triangular prism, first determine the area of the triangular base using the formula ( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} ) of the triangle. Then, multiply the area of the triangle by the prism's height (the length perpendicular to the base) using the formula ( \text{Volume} = \text{Area of base} \times \text{height of prism} ). This will give you the volume of the prism.
It is impossible to find the area of a triangle with no height, if the triangle had no height it would not even be a triangle, just a angle.
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 base + perimeter of triangle*length of prism.
Every prism has a base. For a triangular prism the base is a triangle.
