Landscaping Math: Areas, Mulch & Soil Volumes, Pavers, Plant Spacing & Job Quotes

What you'll build

What you will be able to do

Each lab ends with a concrete result that you build yourself and the checker confirms, cell by cell.

• Measure six planting beds at a Greenhollow Landscapes job. Each bed is split into a rectangle, a part of a circle and a triangle, and you add up the area of each bed and of the whole job.
• Turn areas and depths into cubic feet, cubic yards and cubic metres, count the bags for each material and decide whether Greenhollow buys the mulch in bags or as a bulk delivery.
• Count the pavers for four paved areas of a Greenhollow patio job (with a cut-waste allowance per pattern) and order the crushed base in tonnes and the bedding sand in m³.
• Count the plants for five groundcover and perennial beds on a square grid and on a triangular grid, turn the triangular count into trays per species and price the plants.
• Work out the sod (with waste) and the seed for four lawn zones, order whole pallets and bags for the whole job and compare the cost of sod with seed.
• Calculate the flow and the precipitation rate of five sprinkler zones and turn a weekly water need into minutes per week and per watering day for the controller.
• Turn the quantities of a Greenhollow install job into man-hours with production rates, add a travel and setup allowance, and work out crew hours, labour cost and the number of crew days.
• Price a Greenhollow install job from direct costs with a markup, build the client's seasonal maintenance contract with a bundle discount and monthly payments, and chart where the contract money comes from.
