SURFACE AREA AND VOLUME, , Mensuration:, , It is branch of mathematics which is, concerned about the measurement of, length area and Volume of plane and, Solid figure., , 2. Perimeter, , a) The perimeter of plane figure is, defined as the, , length of the boundary, , b)It's units is same as that of length, j.e. m,cm km., , 3. Area, , a)The area of the plane figure is the, surface enclosed by its boundary, b) It's unit is square of length unit., i.e. m2, km?, , 4 Volume, , Volume is the measure of the amount, of space inside of a solid figure, like a, cube, ball, cylinder or pyramid. Its units, are always "cubic", that is, the number, of little element cubes that fit inside, the figure.
