I think it is 0.4/0.4 but I'm not sure
        
             
        
        
        
{\text{Direction of parabola depends on the sign of quadratic coefficient of a }} \hfill \\
 {\text{quadratic equation}}. \hfill \\
 {\text{For given quadratic equation}}. \hfill \\
 a{x^2} + bx + c = 0 \hfill \\
 {\text{The parabola is in the upward direction if }}a{\text{ }} > {\text{ }}0{\text{ and in downward direction if }}a < 0 \hfill \\
 {\text{Here, the equation of given parabola is }} \hfill \\
 {x^2} - 6x + 8 = y \hfill \\
 \Rightarrow y = \left( {{x^2} - 6x + 9} \right) - 9 + 8 \hfill \\
 \Rightarrow y = {\left( {x - 3} \right)^2} - 1. \hfill \\
 {\text{Thus, the parabola is in the upward direction}} \hfill \\ 
 
        
             
        
        
        
Any multiple of 4 would work.
        
             
        
        
        
Answer:
Step-by-step explanation:
- Mass = Density*Volume
- V = m/d
- V = 378.24/2.76 = 137.04 cm³ (rounded)
