If water weighs 1000 kg per cubic metre, then what is the weight of the box with water?
Consider the following for the next two (02) items that follow :<br>The sides of an open box are 0.5 cm thick and bottom is 1 cm thick. The internal length, breadth and depth are respectively 14 cm, 10 cm and 8 cm. It is completely filled with water.
- A. 1.850 kg ✓
- B. 1.900 kg
- C. 2.050 kg
- D. 2.100 kg
Correct Answer: A. 1.850 kg
Explanation
Volume of water is the internal volume, 1120 cm^3. Since water weighs 1 g/cm^3, the water weighs 1120 gm. Total weight = \text{Box weight} + \text{Water weight} = 730 + 1120 = 1850 gm = 1.850 kg.
