Each side of a cube is measured to be 7.203m. What is (i) the total surface area and (ii) the volume of the cube to appropriate significant figures ? |
|
Answer» SOLUTION :The number of significant FIGURES in the measured length is 4. The calculated area and the volume should THEREFORE be rounded off to 4 significant figures. Surface area of the cube = `6(7.203)^(2)m^(2)` `=311.299254m^(2)` `=311.3 m^(2)` Volume of the cube = `(7.203)^(3) m^(3)` =`373.714754 m^(3)` =`373.7 m^(3)` |
