(a) Volume of a liquid - (v) measuring cylinder. A measuring cylinder is used in a laboratory to measure the volume of a given liquid. Measuring points are marked on the beaker. (b) Area of a leaf - (iii) Graph paper. A graph paper is used to calculate the area of an irregular shape. It has horizontal and vertical lines marked at an equal interval of 1 mm . (c) SI unit of volume - (ii) m 3 . The space occupied by an object is called Volume. It is a three-dimensional measure used to measure the quantity of an object. The SI unit of volume is the cubic metre. (d) SI unit of density - (i) kg m - 3 . The density of a substance is defined as the mass of a unit volume of that substance. d e n s i t y = m a s s v o l u m e (e) SI unit of speed - (iv) m s - 1 . Speed is the distance covered by an object per unit time.
