The first step is to decompose the 3 – dimensional object into rectangles, triangles, circles, squares and label each of the 2-dimensional shapes thus obtained.The following steps are used to find the surface area of a 3 – dimensional object using nets – How can we use the nets to find the surface area of a 3 – dimensional object? Net allows us to see all the 2-dimensional objects that make a 3 – dimensional object. We know now that a net is a pattern made when the surface of a three-dimensional figure is laid out flat showing each face of the figure. How can nets be used to determine surface area? For instance, below is the net diagram of a cylinder – Nets can be formed for any 3 – dimensional shape. In other words, the net of a solid is a diagram drawn on paper which when cut and folded along the lines can be used to construct a solid shape. What are nets?Ī net is a two-dimensional shape that can be folded to make a three-dimensional shape. The surface area of the 3 – dimensional shapes can also be calculated using nets. Each 3 – dimensional shape has its own formula for finding its surface area. The area occupied by a three-dimensional object by its outer surface is called the surface area. Recall that the space occupied by a two-dimensional flat surface is called the area. The surface area of 3 D shapes is similar to the area of 2 D shapes. The surface area of any given object is the area or region occupied by the surface of the object. What is the surface area of 3-dimensional shapes? What is surface area? 3 – dimensional shapes or 3D shapes are the shapes that have all the three dimensions, i.e. One such type of shape is the 3 – dimensional shape. The Sun, the earth and other planets, the mountains and all other things in the world are all of the specific shapes.
The alphabets of English shapes are all shapes of different types. We come across many shapes in our daily lives and kids start recognising these shapes even before actually studying about them. The boundary or outline of an object is called its shape. Using nets to find the surface area of a triangular prism.

We say a triangular prism is semi-regular if its triangular bases are equilateral and the other faces are squares, instead of a rectangle.įormula to Calculate Volume of a Triangular Prism.It has two triangular bases and three rectangular sides.A triangular prism has a total of 9 edges, 5 faces, and 6 vertices which are joined by the rectangular faces.Triangular prism has a triangular cross section.This kind of a prism has its base formed by an irregular polygon eg. This kind of a triangular prism has its base formed by an equilateral triangle. Triangular prisms can also be categorized on the type of the triangle that forms its base. This prism’s bases are not perpendicular to the lateral faces and do not meet at right angles. This is a prism whose bases are perpendicular to the lateral faces, meaning they meet at right angles. Triangular prisms can then be classified based on how their bases and lateral faces intersect. In this case the two ends also known as the bases are triangular in shape. A triangular prism is a three-dimensional solid object in which the two ends are exactly of the same shape.
Ahead of discussing how to calculate the volume of a triangular prism, let’s define what it is.
