RS Aggarwal Solutions for Class 8 Maths Chapter 19 Exercise 19.1 FAQs
What are three-dimensional shapes?
Three-dimensional shapes are solid figures that have length, width, and height. Unlike two-dimensional shapes, they occupy space and have volume. Common examples include cubes, spheres, cylinders, and cones.
What is the difference between a cube and a rectangular prism?
A cube has six faces that are all squares of equal size, whereas a rectangular prism has six faces that are rectangles. All the angles in a cube are right angles, and its edges are all equal, while in a rectangular prism, the edges can be of different lengths.
How do you find the volume of a three-dimensional shape?
The volume of a three-dimensional shape is calculated differently depending on the shape. For example, the volume of a cube is found by cubing the length of one of its sides (side³), while the volume of a cylinder is found using the formula πr²h (where r is the radius of the base and h is the height).
What is the surface area of a three-dimensional shape?
The surface area is the total area of all the surfaces (or faces) of a three-dimensional shape. It is measured in square units. For instance, the surface area of a cube is 6 times the area of one face (6s²), where s is the length of a side.
