The average U.S. farm occupies 435 acres. How many square miles is this? (1 acre = 43,560 ft², 1 mile = 5280 ft)

Key Concepts

Unit Conversion

Unit conversion is the process of converting a quantity expressed in one set of units to another set of units. In this question, we need to convert acres to square miles, which involves understanding the relationships between different units of area and distance. This requires knowing how many square feet are in an acre and how many square feet are in a square mile.

Area Measurement

Area measurement refers to the quantification of a two-dimensional space. In this context, we are dealing with acres and square miles, both of which are units of area. Understanding how to calculate area and the significance of these units is essential for solving the problem accurately.

Dimensional Analysis

Dimensional analysis is a mathematical technique used to convert one set of units to another by using conversion factors. It involves multiplying the quantity by appropriate conversion factors to cancel out the original units and arrive at the desired units. This method is crucial for ensuring that calculations are accurate and that the final answer is expressed in the correct units.
