Dark brown hardwood mulch

Front bed: 24 ft x 6 ft = 144 sq ft. Depth 3 in = 0.25 ft. 144 x 0.25 = 36.00 cu ft
Side bed (triangle): 14 ft x 5 ft / 2 = 35 sq ft. Depth 3 in = 0.25 ft. 35 x 0.25 = 8.75 cu ft
Round bed: radius 4 ft. 3.14 x 4 x 4 = 50.24 sq ft. Depth 2 in = 0.1667 ft. 50.24 / 6 = 8.37 cu ft
Mulch total: 36.00 + 8.75 + 8.37 = 53.12 cu ft
Plus 10%: 53.12 x 1.10 = 58.43 cu ft
In cubic yards: 58.43 / 27 = 2.16 cu yd
Rounded up to the next half yard: 2.5 cu yd

Garden mix (raised beds)

3 beds, each 4 ft x 8 ft = 32 sq ft, so 96 sq ft total. Depth 10 in = 0.8333 ft. 96 x 10 / 12 = 80.00 cu ft
Plus 10%: 80.00 x 1.10 = 88.00 cu ft
In cubic yards: 88.00 / 27 = 3.26 cu yd
Rounded up to the next half yard: 3.5 cu yd

Pea gravel (path)

30 ft x 3 ft = 90 sq ft. Depth 4 in = 0.3333 ft. 90 / 3 = 30.00 cu ft
Plus 10%: 30.00 x 1.10 = 33.00 cu ft
In cubic yards: 33.00 / 27 = 1.22 cu yd
In tons at the supplier's 1.4 tons per yard: 1.22 x 1.4 = 1.71 tons
Rounded up to the next half ton: 2.0 tons

Order list

Dark brown hardwood mulch: 2.5 cu yd x $38.00 = $95.00
Garden mix: 3.5 cu yd x $46.00 = $161.00
Pea gravel: 2.0 tons x $52.00 = $104.00

Materials total: $360.00

We recommend checking the beds again on site before ordering, since any change in depth or size changes these numbers. Happy to rerun the math at a different depth.

Questions for the owner

Is there a delivery fee, and should it be added to the total?
Should sales tax be included in the materials total?
Is labor being quoted separately from this sheet?

What it does

Turns your measurements into the amount of mulch, soil, or stone to order, with the math shown for each area. Handles beds of different shapes, several materials on one job, extra for waste, and the way your supplier sells (by the yard, by the ton, or by the bag).

Use it when: Use when a landscaper needs to work out how much mulch, topsoil, garden mix, gravel, or other stone to order for beds, paths, or raised planters, such as "how much mulch do I need," "figure the yards for this job," or "how many tons of gravel."
