How is the volume of a regularly shaped object calculated?
Volume = Length + Width + Height
Volume = Length x Width x Height
Volume = Length / Width / Height
Volume = Length - Width - Height

1 mL = 10 cm³
1 mL = 1 cm³
1 mL = 0.1 cm³
1 mL = 100 cm³
How can you find the volume of an irregular object?
Use a ruler
Use density
