Help calculating quantities for diy garden job

[Thighdentitycrisis]

can someone please help me work out how much sand, cement and ballast to order?

1. concrete footing for a brick edging 5.5 m long. Edging will be using pavers 5x10x20. I’m going to stand them on 5cm edge.
2. mortar for laying / pointing above edging
3. mortar to lay / point 1 course of 32 bricks (adding to an existing raised bed)

if anyone can help with the maths I would be really grateful, thanks 🙏

If you Google online calculators there are a variety of them for calculating mortar, concrete etc
Sorry I can’t remember which I’ve used in the past. Try a few and then buy enough aggregate/cement etc for the one that estimates the most because I tend to find that they underestimate it if anything.
