IMPORTANT

Mathematics Solutions from Chapter -1 - Representing 3-D Shapes in 2-D

This Chapter covers topics such as Solid Shapes, Faces, Edges and Vertices, Nets for Building 3D Shapes and, Drawing Solids in Flat Surface (2D Drawing of a 3D)

Practice Other Topics from Representing 3-D Shapes in 2-D

This topic covers the calculations for the surface area and volume of an object formed by combining any two basic solids, namely, cuboid, cone, cylinder, sphere and hemisphere. It defines and discusses formulas for the calculation of frustums.

This topic discusses the three terms faces, edges and vertices. It breaks up 2D and 3D objects as a composition of faces, edges and vertices to help students understand shapes better.

This topic explains the concept of surface development for 3D shapes. It challenges students by discussing multiple options for the net of the same object.

Students are expected to visualise 3D objects on paper. The topic explains three techniques, namely, oblique sketches, isometric sketches and visualising objects from a given angle. Exercises make use of multiple techniques and complex objects.
