<span>(a) What is the capacity of the container? Volume = length * width * height V = 4ft * 2ft * 3ft V = 24 ft</span>³ <span> (b) How much material was used to make the container? Surface area = sum of 6 faces of the prism 4 ft x 3 ft = 12 ft</span>² → 12 ft² x 2 = 24 ft² 4 ft x 2 ft = 8 ft² → 8 ft² x 2 = 16 ft² 2 ft x 3 ft = 6 ft² → 6 ft² x 2 = 12 ft² <span> Surface area = 24 ft</span>² + 16 ft² + 12 ft² = 52 ft²
