You measure one edge of a cube using a meter stick marked in centimeters. Unfortunately, the edge is longer than 1 m. You mark the 1-m point on the cube edge with a pen and then, using a 15-cm ruler marked in millimeters, measure the remaining distance to be 1.40cm.

(a) What is the length of the edge in centimeters?

(b) What is the volume of the cube in cubic centimeters? (Remember, the lengths of all edges of a cube are equal.) Watch your significant figures. Use scientific notation if you have to.

(c) The cube has a mass of 111 kg. What is its density in grams per milliliter? Watch your significant figures.

Actually, I did this for another student; however, you posted under that same question that you had the same problem. My answer to you is the same as to the other student.

Miranda and Sally are apparently the same person.
