Benito made a wooden box to grow herbs on his patio. The box is 16 inches wide, 12 inches tall, and 28 inches long. He plans to fill the box exactly two-thirds full with potting soil. What volume of soil does Benito need? I know how to do this I just need to know if the two-thirds part is trying to throw me off

To answer this question you will need the volume of the wooden box.

Then you will need to find out what 2/3 of that volume is because that is how full the soil will be.

V = 2/3 (16 x 12 x 28)

V = 3584 in.³

Another way to calculate this would be to find 2/3 of the Height (2/3 x 12 = 8 in) and use this in your calculation for the height.
