Set up and solve contextual measurement problems that require choosing the correct geometric formula and units.
Pick a sensible unit and scale for geometry modeling
Problem
A \(24~\text{ft}\) by \(12~\text{ft}\) by \(5~\text{ft}\) backyard pool is modeled as a rectangular prism. State the most sensible unit for its volume.
Big Picture
What this problem is really about
Let both dimensional type and practical scale determine the unit. Pool capacity is three-dimensional, and its length, width, and depth are all expressed in feet, so multiplying them produces the third power of that same unit. A merely linear unit has the wrong dimension, while very small or enormous scales are impractical for a backyard pool.
