Convert the following quantities into SI units with the correct number of significant figures. (e) 978.3 yd³

Guida verificata passo dopo passo

Identify the conversion factor from cubic yards to cubic meters. 1 yard is equal to 0.9144 meters, so 1 cubic yard is equal to (0.9144)^3 cubic meters.

Calculate the conversion factor: (0.9144)^3. This will give you the number of cubic meters in one cubic yard.

Multiply the given volume in cubic yards (978.3 yd^3) by the conversion factor obtained in the previous step to convert it to cubic meters.

Determine the number of significant figures in the original measurement (978.3 yd^3). Since there are four significant figures, ensure that your final answer in cubic meters also has four significant figures.

Express the final result in cubic meters with the correct number of significant figures.
