Drag the corner of the part to solve this.

could you use a plugin like resizealign?

Oh I see your issue. Yeah use resize align like @lordhollowick said

Personally, I’d want to rotate the selected grass part to align to the top face of the dirt wedge, and then use 2 more wedge parts to connect the grass pieces. Stravant’s GapFill plugin will fit these wedges for you. If you just overlap the grass block parts, the tilted one will end up thinner (top to bottom), and if grass part faces perfectly overlap, there will be ugly z-fighting because of the texture.
