The two triangular faces are congruent, meaning they have the same dimensions. As there are three identical rectangular faces, we can calculate the combined area as the perimeter of the base times the height (Ph). Each rectangle’s area is calculated by multiplying its length (the same as the hypotenuse of the triangular base) by its width (which is the height of the prism). As mentioned, a right triangular prism has five faces: two triangular faces and three rectangular ones.įirst, let’s focus on the three rectangular faces. The formula for the surface area of a right triangular prism isn’t plucked out of thin air it is derived logically from the properties of the shape. The formula to calculate the surface area of a right triangular prism is quite straightforward: Surface Area = (Perimeter of the base * Height) + 2 * (Area of the base triangle) Deriving the Formula for Surface Area of a Right Triangular Prism Formulas for Surface Area of a Right Triangular Prism While surface area measures the total area that the surface of an object occupies, volume is a measure of the space that the object occupies or can contain, typically measured in cubic units. Surface area and volume are two vital concepts in geometry, but they serve different purposes. Difference Between Surface Area and Volume of a Right Triangular Prism The key is to break it down into smaller, manageable parts – the triangles and the rectangles – and then add those areas together.
How to calculate the Surface Area of a Right Triangular Prism?Ĭalculating the surface area of a right triangular prism isn’t as daunting as it might first appear. For a right triangular prism, this includes the areas of the two triangular ends and the three rectangular sides. The surface area of a geometric shape is simply the sum of the areas of all its faces. When you put these faces together, you form the prism’s surface. The other three faces, which are rectangles, connect these triangles.
The base and top faces are congruent right triangles, meaning they have the same size and shape. When it comes to a right triangular prism, there are a few unique properties. It is measured in square units and is the sum of all the areas of all shapes that cover the surface of the object. In mathematical terms, the surface area is the total area that the surface of an object occupies. If you’ve ever painted a room, wrapped a present, or put up a tent, you’ve already dealt with the concept of surface area, even if you didn’t realize it at the time. The shape is called a prism because the cross-section (the shape you get if you slice it parallel to the base) is always the same right triangle. Strictly speaking, a right triangular prism is a five-faced polyhedron whose base and top are identical right triangles, and whose other three faces are rectangles. The ‘right’ in the name indicates that the triangle at the ends is a right triangle, meaning it has one angle that measures exactly 90 degrees. You’ve just visualized a right triangular prism. Imagine a three-dimensional object where the two ends look like triangles and the sides are rectangles. Welcome to another exciting topic in our ever-growing series at Brighterly!
