Answer
Answer key: Raised Bed Soil worksheet
Calcapedia 1. Soil to buy: 1,252.63 L
Area inside the bed = length × width
Volume of one bed = area × depth (cm ÷ 100 gives meters)
Multiply by the number of beds and convert to liters (1,000 L per m³)
Add 9% for settling
Divide by the bag size, then round up to whole bags
2. Soil to buy: 45.79 ft³
Area inside the bed = length × width
Volume of one bed = area × depth (inches ÷ 12 gives feet)
Multiply by the number of beds
Add 11% for settling
Convert to cubic yards for a bulk order (27 ft³ in 1 yd³)
Divide by the bag size, then round up to whole bags
3. Soil to buy: 1,281.28 L
Area inside the bed = length × width
Volume of one bed = area × depth (cm ÷ 100 gives meters)
Multiply by the number of beds and convert to liters (1,000 L per m³)
Add 10% for settling
Divide by the bag size, then round up to whole bags
4. Soil to buy: 49.05 ft³
Area inside the bed = length × width
Volume of one bed = area × depth (inches ÷ 12 gives feet)
Multiply by the number of beds
Add 9% for settling
Convert to cubic yards for a bulk order (27 ft³ in 1 yd³)
Divide by the bag size, then round up to whole bags
5. Soil to buy: 15.69 ft³
Area of a round bed = π × (diameter ÷ 2)²
Volume of one bed = area × depth (inches ÷ 12 gives feet)
Multiply by the number of beds
Add 7% for settling
Convert to cubic yards for a bulk order (27 ft³ in 1 yd³)
Divide by the bag size, then round up to whole bags
