Final answer:
The volume of a rectangular prism is found by multiplying its length, width, and height. A specific example provided estimates the volume of a small box at approximately 11.4 cm³, with an understanding of measurement uncertainty. Conversion factors are important for unit consistency in volume calculations.
Step-by-step explanation:
The question asks about calculating the volume of a rectangular prism. To find the volume of a rectangular prism, we multiply its length (L), width (W), and height (H).
The given details may have a typo with '21³'. Assuming 'L x 2L x L', the correct expression should be '2L³' as shown in the reference information provided.
However, if we look at another piece of information given, which describes the dimensions of a small rectangular box with sides 1.80 cm, 2.05 cm, and 3.1 cm, we would calculate the volume by multiplying these dimensions together. Therefore, the volume (V) of that box would be V = 1.80 cm x 2.05 cm x 3.1 cm = 11.457 cm³, which is approximately 11.4 cm³ factoring in the uncertainty of measurement. Conversion factors are also explained, converting inches to feet, as well as the relationship between cubic decimeters and liters, which is essential when dealing with different units of volume. Lastly, the reference to the 'volume of a block in cubic meters' with certain dimensions would require converting the centimeter dimensions to meters before calculation, as volume calculations must be in consistent units.
