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

Given, side of the cube, `a= 7.203m`
Total surface area is `S= 6a^(2)= 6xx(7.203)^(2) m^(2)`
`=311.299254 m^(2)`
`= 311.3 m^(2)` (rounded off to 4 significant figures)
Volume, `V= a^(3)`
`=(7.203)^(3)= 373.714754 m^(3)`
`=373.7 m^(3)` (rounded off to 4 significant figures).
