Type: Match the Following-match the column-Hard-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Surface area of a cube | (i) 1.688 g/cm³ |
| (b) Volume of a cube | (ii) 373.7 m³ |
| (c) Density of a substance | (iii) 311.3 m² |
| (d) Rounding of 2.745 | (iv) 2.74 |
A
a-iii, b-ii, c-i, d-iv
B
a-ii, b-iii, c-i, d-iv
C
a-iii, b-i, c-ii, d-iv
D
a-iv, b-ii, c-iii, d-i
Correct Answer
Option A
Detailed Explanation
The surface area of the cube is calculated to be 311.3 m² and the volume to be 373.7 m³ using significant figures, as noted in the NCERT context. The density is derived from the mass and volume, leading to 1.688 g/cm³, and 2.745 rounds to 2.74 following the rules for rounding.
