These solutions provide a detailed answer to all the questions available in the RS Aggarwal textbook. Cube &amp; cuboid are three-dimensional shapes that comprise 6 faces, 8 vertices, and 12 edges.<\/p>\n<p>The main difference between them is a cube has all its sides equal whereas the length, width, and height of a cuboid are different. The shape of the cube &amp; cuboid looks almost similar but has different properties. These solutions help the students by providing them the detailed answers with examples after each question. These solutions also assist the students to have a proficient studying pattern with which they can secure higher marks in the Maths exam.<\/p>\n<p>Access <a href=\"https:\/\/www.kopykitab.com\/blog\/rs-aggarwal-solution-class-8-chapter-20-volume-surface-area-of-solid\/\" target=\"_blank\" rel=\"noopener noreferrer\">RS Aggarwal Class 8 Maths Chapter 20 Solutions<\/a> PDF<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_47_1 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"ez-toc-toggle-icon-1\"><label for=\"item-69e8ebfe43f96\" aria-label=\"Table of Content\"><span style=\"display: flex;align-items: center;width: 35px;height: 30px;justify-content: center;direction:ltr;\"><svg style=\"fill: #000000;color:#000000\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #000000;color:#000000\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/label><input  type=\"checkbox\" id=\"item-69e8ebfe43f96\"><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 eztoc-visibility-hide-by-default' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.kopykitab.com\/blog\/rs-aggarwal-class-8-maths-chapter-20-ex-20-1-solutions\/#download-rs-aggarwal-class-8-maths-chapter-20-ex-201-solutions\" title=\"Download RS Aggarwal Class 8 Maths Chapter 20 Ex 20.1 Solutions\">Download RS Aggarwal Class 8 Maths Chapter 20 Ex 20.1 Solutions<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.kopykitab.com\/blog\/rs-aggarwal-class-8-maths-chapter-20-ex-20-1-solutions\/#important-definition-for-rs-aggarwal-class-8-maths-chapter-20-ex-201-solutions\" title=\"Important Definition for RS Aggarwal Class 8 Maths Chapter 20 Ex 20.1 Solutions\">Important Definition for RS Aggarwal Class 8 Maths Chapter 20 Ex 20.1 Solutions<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"download-rs-aggarwal-class-8-maths-chapter-20-ex-201-solutions\"><\/span><strong>Download <\/strong><strong>RS Aggarwal Class 8 Maths Chapter 20 Ex 20.1 Solutions<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div id=\"example1\" style=\"text-align: justify;\">&nbsp;<\/div>\n<p style=\"text-align: justify;\"><style>\n.pdfobject-container { height: 500px;}<br \/>\n.pdfobject { border: 1px solid #666; }<br \/>\n<\/style><\/p>\n<p style=\"text-align: justify;\"><script src=\"https:\/\/www.kopykitab.com\/_utility\/js\/pdfobject.min.js\"><\/script><br><script>PDFObject.embed(\"https:\/\/www.kopykitab.com\/blog\/wp-content\/uploads\/2021\/01\/RS-Aggarwal-Class-8-Maths-Chapter-20-Ex-20.1-Solutions.pdf\", \"#example1\");<\/script><\/p>\n<p><a href=\"https:\/\/www.kopykitab.com\/blog\/wp-content\/uploads\/2021\/01\/RS-Aggarwal-Class-8-Maths-Chapter-20-Ex-20.1-Solutions.pdf\">RS Aggarwal Class 8 Maths Chapter 20 Ex 20.1 Solutions<\/a><\/p>\n<h2><span class=\"ez-toc-section\" id=\"important-definition-for-rs-aggarwal-class-8-maths-chapter-20-ex-201-solutions\"><\/span><strong>Important Definition for <\/strong><strong>RS Aggarwal Class 8 Maths Chapter 20 Ex 20.1 Solutions<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li><strong>Cube<\/strong><\/li>\n<\/ul>\n<p>It is a 3D figure that is defined as the XYZ plane.
