Then subtract the size of the smaller TV from the size of the bigger TV to find the size difference: 4800 square inches - 4200 square inches = 600 square inches. Then multiply the size difference by the weight per square inch to find the weight difference: 600 square inches * 4 oz / square inch = 2400 oz. Then divide the weight difference in ounces by the number of ounces per pound to find the weight difference in pounds: 2400 oz / 16 oz / pound = 150 pounds.
