1.How could you measure the volume of a marble with a graduated cylinder? A. Drop the marble in a cylinder with water and read the scale B. Measure the water level both before and after you place the marble in the water. Subtract the two numbers to get the marbles volume. C. Place the marble in the cylinder and weigh them on a triple beam balance D. Read the scale after putting water into the graduated cylinder.
