Answer: h = 9
Explanation:
To find the value of h when p=3, m=6, and n=20, we can substitute these values into the given formula:
H = p√(m^2 + n)
H = 3√(6^2 + 20)
H = 3√(36 + 20)
H = 3√56
H = 3 × 2√14
H = 6√14
Therefore, the value of h is 6√14, which is approximately equal to 9 when rounded to the nearest integer.
