Class 8th of CBSE

About Course
In the previous chapter, we learned about mensuration in two-dimensional, which means the study of properties like areas and perimeter of plane figures like squares, cuboids, circles, etc. But if we include a third dimension in this plane figure, it becomes three-dimensional. Now it contains height
also. the figure now becomes a solid object like a cube, cuboid, cylinder, etc. The concerned study now
becomes three-dimensional, or in other words, mensuration in three dimensions. In this
chapter, we will learn about the volumes and surface areas of solid objects.
