1 answer

To determine how much deeper the hole needs to be to meet the required depth of 24 inches, you can subtract the current depth from the required depth.

  1. Required depth: 24 inches
  2. Current depth: 19 7/8 inches

First, convert 19 7/8 inches to a decimal or a fraction:

19 7/8 inches = 19.875 inches

Now, calculate the difference:

\[ 24 - 19.875 = 4.125 \text{ inches} \]

So, the hole needs to be 4.125 inches deeper, which is equivalent to 4 inches and 1/8 inch.
