Match the items in column-I to the items in column-II. Column-I Column-II i. Area (a) light year ii. Distance (b) m 3 iii. Density (c) m 2 iv. Volume (d) kg v. Mass (e) kg / m 3

i. Area- (c) m 2 The area of a figure is the region covered by the boundary of the figure. Its SI unit is square metre or m 2 . For a rectangle, it is given by the product of its length and breadth. ii. Distance- (a) light year One light year is defined as the distance travelled by light in vacuum during the period of one year. iii. Density- (e) kg / m 3 Density of a substance is defined as the mass of the substance contained in unit volume. The SI unit of density is kg / m 3 . iv. Volume- (b) m 3 The amount of space occupied by a three-dimensional object is known as its volume. The SI unit of volume is cubic metre or m 3 . v. Mass- (d) kg Mass is the amount of matter present in a body. The SI unit of mass is kg . Column-I Column-II i. Area (c) m 2 ii. Distance (a) light year iii. Density (e) kg / m 3 iv. Volume (b) m 3 v. Mass (d) kg

Match the items in column-I to the items in column-II: Column-I Column-II i. Area (a) g cm 3 ii. Length (b) measuring jar iii. Density (c) amount of a substance iv. Volume (d) rope v. Mass (e) plane figures

i. Area - (e) plane figures The area of a figure is the region covered by the boundary of the figure. The area of regularly shaped plane figures can be calculated using the relevant formulae. ii. Length - (d) rope Length is a fundamental quantity. A rope can be used to determine the length of a curved line. iii. Density - (a) g cm 3 The density of a substance is defined as the mass of the substance contained in unit volume ( 1 m 3 ). The CGS unit of density is g cm 3 . iv. Volume - (b) measuring jar The volume of any liquid is equal to the space that it fills and it can be measured using a measuring cylinder or measuring beaker. v. Mass - (c) amount of a substance Mass is the amount of matter present in a body. The SI unit of mass is kg . Column-I Column-II i. Area (e) plane figures ii. Length (d) rope iii. Density (a) g cm 3 iv. Volume (b) measuring jar v. Mass (c) amount of a substance
