Why this matters

How much paint for that wall? How much water in that tank? How much cardboard to build that box? Mensuration is the maths of practical measurement.

The instant you plan any real-world project — from a farm to a factory — you're doing mensuration. It is the friendliest bridge between school maths and useful adult skills.
