Question

each side of a cube is measured to be 7.203 m . what is total surface area and the volume of the cube to appropriate significant figures?

Answer 1

Hey,
Total surface area of cube=6*side^2
=6*(7.203)^2
=311.2993m^2
And,
Volume = side^3
=(7.203)^3
=373.715m^3.

Hope this helps you!!

Answer 2

The number of significant figures in the measured length is 4. The calculated area and the volume should therefore be round off to 4 significant figures.

Surface area of the cube

= 6(7.203)² m²

= 311.299254 m²

= 311.3 m²

Volume of the cube

= (7.203)³ m³

= 373.714754 m³

= 373.7 m³
