Describe a strategy you can use to estimate then find the volume of this textbook.textbook measures 21cm by 28 cm and 2.5 thick.what problems may you have finding the volume

What problems are you having trying to solve this problem?

To estimate and find the volume of the textbook, you can use the following strategy:

1. Start by estimating the volume: Since the textbook is approximately rectangular, you can estimate its volume by multiplying the length, width, and height together. In this case, the length is 21 cm, the width is 28 cm, and the height (thickness) is 2.5 cm.
Estimate: Volume ≈ Length × Width × Height = 21 cm × 28 cm × 2.5 cm = 1470 cm³ (approximately)

2. Check for any potential issues in finding the volume:
- Non-rectangular shape: If the textbook has an irregular shape, estimating the volume by using length, width, and height may result in inaccuracies. In such cases, you could consider using water displacement method or breaking it down into regular shapes and adding their volumes.
- Measurement units: Make sure all dimensions are measured in the same unit. In this case, all the dimensions are given in centimeters (cm), so there's no issue.

3. Find the actual volume: To obtain a more precise volume, it's recommended to measure each side of the textbook separately. In this case, we already have the measurements. Multiply the length, width, and height together to find the volume.
Volume = Length × Width × Height = 21 cm × 28 cm × 2.5 cm = 1470 cm³

By following this strategy, you can estimate and find the volume of the textbook. It's important to be aware of potential issues, such as irregular shape or unit inconsistency, which could affect the accuracy of the volume calculation.
