1. If the length, breadth, and height of a right rectangular prism are in the ratio 3:2:1 and its total surface area is 88 square centimeters, then what is its volume?

(a) 120 cubic cm (b) 64 cubic cm (c) 48 cubic cm (d) 24 cubic cm

2. The length, breadth, and height of a cuboid are in the ratio 4:3:2. If its total surface area is 468 square meters, find the volume of the cuboid.

3. Three oil drums contained 800 liters, 725 liters, and 575 liters of oil, respectively. The oil from these drums was poured into a rectangular container, resulting in a depth of 7 decimeters. Given that the length-to-width ratio of the container is 4:3, determine the length and width of the container.

4. A rectangular box has a length, width, and height ratio of 3:2:1. If its volume is 384 cubic centimeters, find the total surface area of the box.

5. If the length, breadth, and height of a rectangular box are in the ratio 3:2:1 and its volume is 384 cubic centimeters, calculate and write the total surface area of the box.

6. Three household kerosene oil drums contained 800 liters, 725 liters, and 575 liters of oil respectively. The oil from these three drums was poured into a rectangular container, which then had a liquid depth of 7 decimeters. If the ratio of the length to the breadth of the rectangular container is 4:3, calculate and write the length and breadth of the container. Also, if the depth of the container were 5 decimeters instead, determine whether it could hold 1620 liters of oil.

7. Here is the translated version of the table and instruction: **Find the median diameter (in mm) from the following frequency distribution of pipe diameters.**
