It depends of course a bit on the size of the wheelbarrow and on how high you want to pile up the sand. But a typical wheelbarrow might hold about 85 liters of sand. 1 cubic meter equals 1,000 liters. So you would need about 12 wheelbarrow loads to get 1 cubic meter.
It depends on the weight of the sand, but on average, a 50 lb bag of sand equals approximately 0.0227 cubic meters. So, roughly there would be around 44 bags in 1 cubic meter of sand.

The density of chromite sand can vary, but on average it is around 2.7 tons per cubic meter. Therefore, 1 ton of chromite sand would be approximately 0.370 cubic meters.

The weight varies; but if it's dry sand, the cubic meter will weigh around 1500 kilos.
It isn't clear what "units" you are talking about.
