Solution
Solution Steps
Solution Approach
1.1.1 i) The unit used to measure volume in the given context is typically cubic centimeters (cm³), which is option B. ii) The formula to calculate the area occupied by the water dispenser on the floor is the area of a rectangle, which is length times breadth, option C.
1.1.2 To determine the radius of the base of the water bottle, we need additional information such as the volume or the height of the bottle. Without this information, we cannot calculate the radius.
1.1.3 The total amount of water recommended to drink daily is already given as 1920 ml.
Step 1: Volume Unit
The unit used to measure volume in the context of water dispensers is cubic centimeters, denoted as \( \mathrm{cm}^3 \). Therefore, the answer is B.
Step 2: Area Formula
The formula used to calculate the area occupied by the water dispenser on the floor is given by the product of its length and breadth, expressed as:
\[
\text{Area} = \text{length} \times \text{breadth}
\]
Thus, the answer is C.
Step 3: Total Daily Water Intake
The total amount of water recommended to drink daily is calculated as follows:
\[
\text{Total Daily Water} = 8 \text{ glasses} \times 240 \, \mathrm{ml/glass} = 1920 \, \mathrm{ml}
\]
