Worked concrete calculations

Follow every input, conversion, and rounding step

Two scenarios separate geometry, user-selected extra, label yield, and whole-bag packaging.

Imperial slab5 min example

10 × 10 ft concrete slab with explicit extra and bag yield

Follow a user-entered 4-inch thickness from 33.333 cubic feet through an 8% extra to 60 bags at 0.60 cubic foot each.

Metric post holes6 min example

Calculate six 0.30 m holes, 0.80 m deep, around 0.10 m round posts with fixed π, 5% extra, and 0.012 m³ label yield.
