A bar of gold is a cuboid. It is measured as 8.6 cm by 4.1 cm by 2.4 cm. All measurements are correct to the nearest millimeter. What is the largest possible volume of the bar of gold?
85.17 cm³
85.18 cm³
85.19 cm³
85.20 cm³
Explanation
For the largest volume, use the upper bounds of each measurement. Upper bounds: 8.65cm, 4.15cm, 2.45cm. Volume = 8.65 * 4.15 * 2.45 = 87.83cm³
