Question

It’s spring season once more and Jo wants to grow colourful flowering plants. She decides to make 16 raised flower beds, each measuring 1m x 4m x 0.5m.

(i) Calculate the volume of soil required to fill the 16 flower beds.
(ii) If soil is available only in 40 litre bags, how many such bags will she have to buy to make the 16 flower beds?​

Answer 1

(i) 32 cubic meters, (ii) 800

Explanation:

(i) 1 x 4 x 0.5 = 2 m3, x 16 = 32

(ii) 1000 litre per m3 = 32,000 litres required divided by 40 = 800 bags.
