Final answer:
The statement is true; measuring plans with approximate dimensions can quickly estimate material costs for a job when precision is not crucial. Rounding measurements may yield less reliable results, but it is often sufficient for certain tasks like rough estimations. A tape measure can be used for more precise measurements when needed.
Step-by-step explanation:
The statement is true: when accuracy is not required and approximate dimensions are adequate, measuring plans is a quick method of taking off material for estimating the cost of a job. Utilizing approximate measurements can be a practical approach in various situations where the exact size or amount of materials is not critical. For example, if your hand measures 10 cm across, you can use it to estimate the width of your desk by measuring how many hand lengths span across it.
However, it's important to note that as you round measurements or use less precise methods, the resulting figure might be less reliable. In scenarios that do not require high precision, like a rough cost estimate for a construction project, approximate values can be sufficient. In contrast, more precise measurements are crucial in scientific work or where accuracy is paramount. A tape measure is a versatile tool that can be used in these situations, as it can measure in both feet and meters and is flexible enough to handle different measurement needs.
