While measuring the length of a wooden box, the reading at one end is 1.5 cm on a scale and the other end is 4.7 cm. What is the length of the wooden box?

Options

A. 4.7 cm
B. 1.5 cm
C. 3.2 cm
D. 6.2 cm

Explanation

To find the length of the wooden box, we need to follow these steps:

### Step-by-Step Solution:

1. **Identify the Readings**: We have two readings from the scale. The reading at one end of the box is 1.5 cm and the reading at the other end is 4.7 cm.

2. **Calculate the Length**: The length of the wooden box can be calculated by finding the difference between the two readings. This is done using the formula:
\[ \text{Length of the box} = \text{Reading at the other end} - \text{Reading at one end} \]

3. **Substitute the Values**: Now, substitute the values we have into the formula:
\[ \text{Length of the box} = 4.7 \, \text{cm} - 1.5 \, \text{cm} \]

4. **Perform the Calculation**: Now, we will perform the subtraction:
\[ 4.7 \, \text{cm} - 1.5 \, \text{cm} = 3.2 \, \text{cm} \]

5. **Conclusion**: Therefore, the length of the wooden box is 3.2 cm.

### Final Answer:
The length of the wooden box is **3.2 cm**.
