• say for example : a glass.. it would sound normal to you if i say that i have drunk one glass of water
• yes you are right
• i think the volume is the amount of space that something contains or fills
• as you know what is volume you must be knowing the surface and lateral area also...hence let us continue with the certain formulas which are very important and will helo you to find the solution of every problem
• formulas : (CUBE AND CUBOID)CUBE=====>>> V=S^3 SA=6S^2 LA=4S^2CUBOID=====>>> V=LBH SA=2(lb+bh+lh) LA= 2(L+B)H
