Final answer:
The total cost of 2.3 cubic meters of soil at $27 per cubic meter is $62.10, calculated by multiplying 2.3 by $27.
Step-by-step explanation:
To calculate the total cost of 2.3 cubic meters of soil at $27 per cubic meter, you multiply the quantity of soil by the cost per unit:
- First, identify the price per cubic meter: $27.
- Then, multiply that price by the total volume of soil required: 2.3 cubic meters.
- Calculate the total: 2.3 m³ × $27/m³ = $62.10.
Therefore, the total cost for 2.3 cubic meters of soil is $62.10, which corresponds to option a) $62.10.
