An exercise plan requires 18 g of pure live seed per m² over 400 m². A seed lot has 95% purity and 80% germination. Define pure-live-seed fraction as purity fraction × germination fraction. Add 5% to the calculated bulk-seed requirement and buy 10 kg bags. No species or real application rate is recommended. Calculate the bulk seed needed before reserve in kilograms. Keep intermediate values unrounded; round the final answer to 4 decimal places if needed.
