To calculate the volume of concrete required for a slab, the formula for volume in cubic feet is:
Volume=Length×Width×Depth\text{Volume} = \text{Length} \times \text{Width} \times \text{Depth}Volume=Length×Width×Depth
Given:
Volume=13.5×10×0.5=67.5 cubic feet\text{Volume} = 13.5 \times 10 \times 0.5 = 67.5 \text{ cubic feet}Volume=13.5×10×0.5=67.5 cubic feet
To convert cubic feet to cubic yards (since 1 cubic yard = 27 cubic feet):
Cubic Yards=67.527=2.5 cubic yards\text{Cubic Yards} = \frac{67.5}{27} = 2.5 \text{ cubic yards}Cubic Yards=2767.5=2.5 cubic yards
Upon review, there seems to be a mistake in the available options, as the calculation yields 2.5 cubic yards, which would suggest a correct answer is not listed. Given the options provided, I would selectD. 2.5 cubic yardsas the closest accurate calculation. However, if constrained to the given answers,B. 2.0 cubic yardsis incorrect by calculation standards.
