Select the two correct answers M= D x V Mass equals density divided by volume Mass equals density times volume D=M divided by V M=D divided by V When trying to find the volume of a regular shaped object (idk how to work that!) , we use a ruler. What method would we use to find the volume of an irregular object? Type answer (25 letters) What is the variable that the experimenter changes during the experiment. Type answer (20 letters) If plants are watered, then the growth height will increase? Check off the correct answer.
