Answer :
To solve these two questions, let's take them one at a time.
### Converting 67 inches to centimeters
1. Know the conversion factor: 1 inch is equal to 2.54 centimeters.
2. Multiply the number of inches by the conversion factor:
[tex]\[
67 \, \text{inches} \times 2.54 \, \text{cm/inch} = 170.18 \, \text{cm}
\][/tex]
So, 67 inches is equal to 170.18 centimeters. Therefore, the correct option is:
- c. 170.18 cm
### Comparing a pound of water and a kilogram of water
1. Understand the weights:
- 1 pound is approximately 0.453592 kilograms.
- 1 kilogram is exactly 2.20462 pounds.
2. Comparison:
- Since 1 kilogram is more than 2 pounds, and 1 pound is approximately 0.45 kilograms, it's clear that a kilogram of water is heavier than a pound of water.
So, the statement "A pound of water weighs more than a kilogram of water" is False.
Finally, summarizing the answers:
- 67 inches is 170.18 cm.
- A pound of water weighs less than a kilogram of water (False).
