Using Scientific Equipment
Triple Beam Balance, Calculating Volume of a Regular Object

Using a Triple Beam Balance
1. Wipe off the pan

2. Move all of the weight to zero (the far left)

3. Adjust the tare knob ( or adjustment knob) until the pointer lines up with the zero mark Tare knob or adjustment knob

4. Carefully place the object on the pan. Leaving the weights at zero for now.

5. Move the weight on the bars until the pointer lines up with the zero mark. *For large or heavy objects start with the large weight that moves in 100 gram increments * For small and lighter objects start with the smaller weights that move in 1 gram or 10 gram increments

Using a Triple Beam Balance
6. After finding which heaviest weight on the 100 gram bar still allows the pointer to point above the zero mark, start adding smaller amounts from the other bars. Do this first with the weights on the 10 gram bar then the one gram bar until the pointer is lined up with the zero line NOTE: The one gram bar is very sensitive. Touch it very carefully and move the weight slowly

Calculating the Volume of a Regular Object
Calculating the volume of a regular object is easy. Just multiply Length X Width X Height Width Length Height

Calculating the Volume of a Cubic Object
For instance, if you have a cube that is 4 centimeters long, 4 centimeters wide and 4 centimeters high you would multiply 4cm X 4cm X 4cm = 64 cubic centimeters
