## FAQs on RD Sharma Class 8 Solutions Chapter 21 - Volumes Surface Area Cuboid Cube (Ex 21.1) Exercise 21.1

**1. What are some RD Sharma Class 8 surface area and volume solution sources that I should use?**

The RD Sharma textbook for RD Sharma class is RD Sharma Notes which contains all of the important formulas, RD Sharma techniques, and RD Sharma Solutions needed for RD Sharma exams. Other RD Sharma textbooks which are popular amongst RD Sharma students include RD Sharma Lecture, RD Sharma Practice, and RD Sharma PDF.

**2. What should I do if I find a surface area and volume problem from RD Sharma difficult?**

If you get stuck on a problem, the best thing is to put it aside and move on. RD Sharma problems are tough, so there's no shame in getting stuck! It is better to revise the concept. RD Sharma solutions can be frustrating if you're not sure where to start, but don't let that discourage you from your RD Sharma Class mission of mastering RD Sharma Solutions.

**3. What is cube and cuboid and how to calculate their volumes?**

A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. It has 6 faces, 12 edges, and 8 vertices.

If “a” is the edge of the cube , then its volume is given by a^{3}.

A cuboid is a convex polyhedron bounded by six quadrilateral faces. Its volume is calculated by the Formulae : LxBxH , where

**L**= Length of the cuboid

**B**= Breadth of the cuboid

**H**= Height of the cuboid.
