The number of shovels of sand in a wheelbarrow can vary depending on the size of the shovel and the size of the wheelbarrow. On average, a standard wheelbarrow can hold about 6-8 shovels of sand. It is important to consider the volume of the shovel and the wheelbarrow to determine the exact number of shovels needed to fill it.
sand=2*Weight of Cement water=cement/2
It would depend on the size of the shovel, but on average, a 25kg bag of soft sand would fill around 4-5 medium-sized shovels.
