1) find the volume of the rectangle ( lxwxh=v)
lengh= 8.1 cm
width=6.2 c
height= 3.3 cm
2) the original volume of the water is 70 ml. if you dropped a rock into the water and the volume becomes 72 ml. what is the volume of he rock?
3)why does the first method (lxwxh=v) for determining volume work only for a regularly shaped object?
4)will the water displacement method for determining volume work for any object or just an irregularly shaped one? why?
5) is one method of measurement more accurate than the other? why or why not?
6)would the water displacement method of measurement work for a cube of sugar? what about a cork? why or why not?
7)what did you find out from this investigation? be thoughtful in your answer.
