Correct answers only ! this is the last day to complete this assignment and i desperately need to finish this assignment with an 100%.

The answer to your question is: letter a

Step-by-step explanation:

data

balls diameter = 0.75 in then radius = 0.375 in

rectangular prism =   length = 3 in width = 3 height = 7.5 in

Formula

Rectangular prism volume = l x w x h = 3 x 3 x 7.7 = 67.5 in³

ball volume = 4/3 (3.1416)(r³) = 4/3 (3.1416)(0.375)³ = 0.220in³

 but   0.220in³ 100 %

             x            190%

  x = 0.418 in³

Finally divide the rectangular prism volume by ball volume

# of balls = 67.5 / 0.418 = 161.4 ≈ 160
