Each side of a cube is measured to be 7.023m. What are the total surface area and volume of the cube to appropriate significant figures.

Explanation

Here l=7.203m Surface area of the cube=`6l^2
A=6(7.203)^2=311.299m^2`
As l has four significant figures as per rule surface area and volume both should have four significant figures.
Rounding off`A=311.3mm^2` volume of the cube `=l^3=(7.203)^3=373.714m^3=373.7m^3`
