To calculate basal metabolic rate (BMR), we need to use the Mifflin-St. Jeor equation:

BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5

First, we need to convert Benjamin's weight and height from imperial units to metric units:

Weight: 170 lbs ÷ 2.2 = 77.3 kg 
Height: 5'10" = 177.8 cm

Now we can plug these values into the equation:

BMR = (10 × 77.3) + (6.25 × 177.8) - (5 × 18) + 5 
BMR = 1,855.025

Therefore, Benjamin expends approximately 1,855 kilocalories per day for basal metabolism.
