So your hole must be deeper by another 2 feet and 6 inches. (or by 30 inches)
Explanation:
1 foot = 12 in
4 feet = 12×4 in
4 ft = 48 in (how deep it should be)
Current depth: 1 foot + 6 in
1 ft = 12in
12in + 6in = 18in (the current depth of your hole)
48in (total) - 18in (current) = 30 in (remaining depth)
30 in = ?ft + ?in
1 foot = 12 in 2ft = 24in 3ft = 36in 4ft=48in
The closest number that is below 30 is 24
We have 24inch = 2ft
And we have 6 inches remaining (30in-24in=6in)
2ft + 6in or 30in remaining
