How much will a yard of soil cover?

Excuse me, could you please clarify for me how much area would a yard of soil be able to cover? I'm trying to get an estimate for a landscaping project I'm working on, and I'm unsure of the exact coverage that a yard of soil provides. Could you elaborate on this for me, or provide a rough approximation of the area that could be covered by this amount of soil? I'd appreciate any information you can provide to help me with my calculations.
