In the backyard of an experimental elementary school, there is a parallelogram-shaped open space with a base of 8.8 meters and a height 3.8 meters shorter than the base. Now I want to spread lawn on this open space. If the cost of lawn per cubic meter is calculated at 25.40 yuan, how much will it cost to cover this open space with lawn?
某实验小学的后院有一块平行四边形的空地，底边为8.8米，高比底边短3.8米．现在想把这块空地上铺上草坪，如果每立方米草坪造价按25.40元计算，这块空地铺满草坪需要多少钱？
