Final answer:
The specific number of yards that one MMC truck can carry within weight limitations isn't provided, but it's typically around 20 tons for long-haul trucks. One would need to know the weight per cubic yard of the material (such as sand) to calculate the volume capacity in yards.
Step-by-step explanation:
The amount of material that one truck at MMC carry within weight limitations is not explicitly stated in the provided information. However, we can infer that if yards are a measurement of volume (a cubic yard), and the typical cargo capacity for a long-haul truck is about 20 tons, then the calculation would involve finding out how many cubic yards of a material like sand can be carried without exceeding this weight limit.
Since the weight per cubic yard of the material is not given, a specific answer cannot be provided. However, for example, if we know the weight of a cubic yard of sand, we can then divide the truck's carrying capacity (20 tons) by the weight of one cubic yard of sand to determine how many cubic yards can fit within those weight limits.
It is worth noting that the cargo capacity may vary depending on the design and purpose of the truck. For instance, modifications for carrying a larger battery could potentially reduce cargo space for material transport.
