How many pieces of plywood, each 0.35 cm thick, are required to make a pile 1.89 m high? Hint. 1.89 m = (1.89x100) cm = 189 cm.

Answer

To find out how many pieces of plywood, each 0.35 cm thick, are required to make a pile 1.89 m high, we can follow these steps:

### Step 1: Convert the height from meters to centimeters
1. We know that 1 meter is equal to 100 centimeters.
2. Therefore, to convert 1.89 meters to centimeters, we multiply by 100:
\[ 1.89 \, \text{m} = 1.89 \times 100 \, \text{cm} = 189 \, \text{cm} \]

### Step 2: Determine the thickness of each piece of plywood
1. The thickness of each piece of plywood is given as 0.35 cm.

### Step 3: Calculate the number of pieces of plywood required
1. To find the number of pieces of plywood needed to reach the height of 189 cm, we divide the total height by the thickness of each piece:
\[ \text{Number of pieces} = \frac{\text{Total height}}{\text{Thickness of each piece}} = \frac{189 \, \text{cm}}{0.35 \, \text{cm}} \]

### Step 4: Perform the division
1. Now we perform the division:
\[ \frac{189}{0.35} = 540 \]

### Conclusion
Thus, the number of pieces of plywood required is **540**.
