Volume of 8 such cubes = 8 volume of one cube = 8 × 64 = 512 cm 3 Hence, the volume of the initial cuboidal block of wood is 512 cm 3. 4. If three solid spherical beads of radii 3 cm, 4 cm, and 5 cm, respectively, are melted into one spherical bead, then find its radius in cm. Solution: Given, Radii of three solid spherical beads: 3 cm, 4 cm ... Volume of Cube The volume of the cube is the space contained in it. Suppose, if an object is in cubical shape and we need to immerse any material in it, say water, then the measure of water in litres to be kept in the object is calculated by its volume . The formula of the volume is given by: The volume of sphere is the amount of space occupied, within the sphere. The sphere is defined as the three-dimensional round solid figure in which every point on its surface is equidistant from its centre.
