Answer 2

Comparison of Area and Volume Measurements

Let's compare the given measurements using the comparison operators greater than (>), less than (<), and equal to (== or =).

1) 400 cm^2 vs 4 dm^2: To compare these two measurements, we need to convert them to the same unit. Since 1 dm (decimeter) is equal to 10 cm, we can convert 4 dm^2 to cm^2 by multiplying it by 100 (10 cm * 10 cm). Therefore, 4 dm^2 is equal to 400 cm^2. So, 400 cm^2 = 4 dm^2.

2) 8000 cm^3 vs 8 dm^3: Similarly, to compare these two measurements, we need to convert them to the same unit. Since 1 dm (decimeter) is equal to 10 cm, we can convert 8 dm^3 to cm^3 by multiplying it by 1000 (10 cm * 10 cm * 10 cm). Therefore, 8 dm^3 is equal to 8000 cm^3. So, 8000 cm^3 = 8 dm^3.

3) 5000 m^2 vs 5 a: To compare these two measurements, we need to convert them to the same unit. 1 a (are) is equal to 100 m^2. Therefore, 5 a is equal to 500 m^2. So, 5000 m^2 > 5 a.

4) 64000 cm^3 vs 8 dm^3: To compare these two measurements, we need to convert them to the same unit. Since 1 dm (decimeter) is equal to 10 cm, we can convert 8 dm^3 to cm^3 by multiplying it by 1000 (10 cm * 10 cm * 10 cm). Therefore, 8 dm^3 is equal to 8000 cm^3. So, 64000 cm^3 > 8 dm^3.

In summary: 1) 400 cm^2 = 4 dm^2 2) 8000 cm^3 = 8 dm^3 3) 5000 m^2 > 5 a 4) 64000 cm^3 > 8 dm^3
