for the volume do the equation length×width×height. so 10×4×2.75
The scale is likely to show the mass is either 270.9g or 245.1g
Step-by-step explanation:
Actual mass = 258g
Percent error = 5% = ±0.05
Mass shown by scale = Actual mass*percent error

Therefore,
Mass shown by scale = 258+12.9 , Mass shown by scale = 258-12.9
Mass shown by scale = 270.9g , Mass shown by scale = 245.1g
The scale is likely to show the mass is either 270.9g or 245.1g
