Using nets to find the surface area of a cubeīefore, discussing the area of a cube using nets, let us observe how many nets for a cube can be possible? There can be 11 different possible nets of a cube.

Let us now see how to find the surface area of a cube using nets. So, the total surface area of a cube = 6 c 2 Total Surface area of a cube = c 2 + c 2 + c 2 + c 2 + c 2 + c 2 = 6 c 2 Now, there are 6 faces in total, all of which have equal areas. Using the formula of finding the area of a square, the area of one face = c 2 Let the length of the edge of the cube be “ c “. Therefore, the area of each face of the cube is equal to square of its edge. Also, we can observe from the shape of a cube that the surface of the cube is in a square shape. We know that a cube has six faces therefore, the total surface area of the cube will be equal to the sum of all six faces of the cube. In other words, it is an extension of a square in a 3D plane.īelow we have a general diagram of a cubeĪ cube has 6 rectangular faces, out of which all are identical.Ī cube has 8 vertices How to find the surface area of a cube? Examples of a cube are sugar cubes, cheese cubes and ice cubes. What is a cube?Ī cuboid whose length, breadth and height are equal is called a cube. Surface area of a cube using netsĬube is a common geometrical shape that we make use of in everyday lives. Let us now use the above steps to find the surface area of some of the common 3 – dimensional shapes using nets. Visualize how the net is to be folded to form the solid and make sure that all the sides fit together properly.Make sure that the solid and the net have the same number of faces and that the shapes of the faces of the solid match the shapes of the corresponding faces in the net.The following points should be kept in mind while expanding a 3-dimensional shape in the form of nets – After fining the area of all the 2-dimensional shapes, the last step is to add up all the area to get the total area which is the surface area of the given 3 – dimensional shape.Now that we have the dimensions of each side, we can find out the area of each 2-dimensional shape that we had obtained in the first step.The next step is to find the dimensions which are the lengths of the sides that would be required to find the surface area.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.
