On calculating using conversions, John can select either the package of wood with (a) 3 pieces of 2000mm each or the one with (d) 6 pieces of 100cm each.
On conversion of units from mm and cm to m:
1m = 100cm
1m = 1000mm
Therefore,
Since John requires 6m of wood to build a diving board, using unit conversions:
3 pieces of 2000mm each:
2000mm = 2m = 2m x 3 = 6m
4 pieces of 1.5 cm each:
1.5cm = 0.015m x 4 = 0.06m
6 pieces of 100 mm each:
100mm = 0.1m x 6 = 0.6m
6 pieces of 100 cm each:
100cm = 1m x 6 = 6m
8 pieces of 200 mm each:
200mm = 0.2m x 8 = 1.6m
Result:
The package with 3 pieces wood of 2000mm each equals to 6m of wood.
Similarly, the package with 6 pieces wood of 100cm each equals to 6m of wood.
