Each side of a cube is measured to be 7.203 m. What is total surface area?

Text Solution

Verified by Experts

Side of cube, a=7.203 m.
So number of significant figures are four.
Surface area of cube =`6a^2`
`6 times 7.203 times 7.203 =311.299`
But our final answer must be rounded to least number of significant figures is four digits.
So surface area of cube=`311.3m^2`
