Volume of Cube
A cube is a region of space formed by six identical square faces joined along their edges. Three edges join at each corner to form a vertex.
Volume of Cube = edge x edge x edge = (a3) cubic units
Example 1: Find the volume of the cube, whose edge length is 3 cm?
Solution:
Volume of Cube = a3 (where a = edge or side length)
Volume = 3 x 3 x 3 = 27 cm3
Example 2: Find the length of the side of the cube whose volume is 1331 cm3?
Solution:
Volume = side x side x side
=> 1331 = a3
Hence, side a = 11 cm.
Volumes – Surface Area & Volumes | Class 9 Maths
If an object is solid then space occupied by such an object is measured and termed as the Volume of the object. In short, the Volume of an object is the measure of the space it occupies, and the capacity of an object is the volume of substance its interior can accommodate. So, if we were to talk of the volume of a cube, we would be considering the measure of the space occupied by the cube.
The Unit of measurement of Volume is the cubic unit.
