Given:

315 pounds = 143 kg

Your own bodyweight = 85 kg

You are squating down 0.5 m (1.5 feet)

Total weigth = 143 + 85kg = 228kg

Potential energy (1 rep) = U = m*g*h = 228 * 9.8 * 0.5 = 1117 Joules

Potential energy 10 reps = 10 * 1117 = 11170 Joules

11170 Joules = 2.7 Calories (kcal)

So, if your body opperates at 100% efficiency, you burn 2.7 Calories (kcal).

In practice you would need 20 ~ 25 Calories, depending the temperature of the room you are in, etc.
