250 40-lb bags, or 187.5 ft³ in bulk.
- Cubic feet187.5
- 40 lb bag count250
- Estimated weight15,278 lb (~7.6 tons)
Step-by-step
- Volume = 25 × 15 × 0.500 = 187.50 ft³.
- Cubic yards = 187.50 ÷ 27 = 6.944 yd³.
- Bag count (0.75 ft³/bag) = 250.
How to use this calculator
- Enter the bed area and depth.
- Use 2-3 inches for top-dressing a lawn, 6 inches for new beds, more for raised beds.
- Compare bagged vs bulk pricing — bulk is dramatically cheaper above 2 yards.
About this calculator
Topsoil for lawn renovation is typically applied at 2-3 inches over an existing surface or 6 inches when building a new bed. Bulk topsoil weighs about 1.1 tons per cubic yard. A 40-lb bag yields roughly 0.75 ft³.
