DENISTY & CALCULATING VOLUME - MODULE #2


 

Find the Volume of a Cube  (L x W x H)





  1. 1
    Measure one side of the cube. If you already know the length of one side of the cube, you can move on. If not, use a ruler to measure the side of the cube. Let's say the side of the cube is 2 inches long.

  2. 2
    Cube the length of the side. Finding the volume of a cube really means finding the area of the base and then multiplying it by its height. Since the area of the base is found by multiplying the length and the width, and the length and the width of a cube are the same, and so is the height, all you have to do is cube the length of one side to find the volume. 2 x 2 x 2, or 23 = 8. 
 
3
State your answer in cubic units. Since volume is the measure of three-dimensional space, you'll have to state your answer in cubic units. Since the original Measurements were made in inches, your final answer should be 8 in.3

STEPS FOR FINDING THE VOLUME OF AN IRREGULAR OBJECT

Steps

  1. 1
    Fill up the graduated cylinder about half way with water. Be sure to tilt the cylinder while pouring water to help prevent bubbles from forming.

  2. 2
    Set down the cylinder on a flat surface at room temperature. If there are bubbles present, wait a few moments for them to pop. Align your eyes with the water level, and take the measurement.
  3. 3
    Remember or write down the measurement you took.
  4. 4
    Tilt the cylinder, and gently slide the object down until it its fully submerged.
  5. 5
    Once again, align your eyes with the water level, and take the new measurement.
  6. 6
    Subtract the new measurement from the original. The difference, is the volume of the object.
