how to return the total value, as an integer, of all the hash values of three hashes, each of which is an element of an array? in ruby

main.rb
# Create an array with three hashes
hashes_array = [
  { key1: 10, key2: 20, key3: 30 },
  { key4: 40, key5: 50, key6: 60 },
  { key7: 70, key8: 80, key9: 90 }
]

# Initialize a variable to hold the total value
total_value = 0

# Iterate over each hash in the array
hashes_array.each do |hash|
  # Iterate over each value in the hash and add it to the total value
  hash.each_value do |value|
    total_value += value
  end
end

# Output the total value
