Measurement · Combined volumes

Add multiple shapes into one cubic-yard order.

Model rectangular prisms, cylinders, triangular prisms, and annular rings independently, then combine them before allowance and pricing.

← Rectangle length →↕ Rectangle width↕ Rectangle depth
← Circle diameter →↕ Ring depth← Inner diameter →
← Triangle base →↕ Triangle height← Prism length →

Transparent calculation

Each shape keeps its own geometry and subtotal.

All shape volumes are calculated in cubic feet, divided by 27, summed, and only then adjusted by the entered order allowance.
