Each side is measured to be 7.203 m. What are the total surface area and the volume of the cube to appropriate significant figures ?

Explanation

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)`
