1.地面装饰：
(1) 20mm厚干混地面砂浆找平层
(3.6-0.06+3.9-0.12) x (6.0-0.12-0.12) =42.16 (m²)
(2)地面：
B房间实木地板: SB= (3.6-0.06+3.9-0.12) x (6-0.12-0.12) +[1.0x0.24+1.0x0.12x0.5] (增加门洞处面积) =42.46m²
(3)踢脚线：
B房间1 20mm高实木踢脚线:
[ (6-0.24) + (3.6+3.9-0.12-0.06) -1.0 (扣门洞) ]x2x0.12+0.24x0.12x2x2 (增加柱侧面踢脚线) +[0.12x2+0.06x2]x0.12 (增加门洞侧面踢脚线) =3.06m²
2.内墙装饰：
干混抹灰砂浆M10粉刷工程量= [ (3.6+3.9-0.12-0.06) + (6-0.24) ]x2x (3.3-0.1) (层高扣除楼板厚度)+0.24x (3.3-0.1) x4 (柱侧壁) -2.1 (门洞尺寸) x1.0x2 (门洞) -1.8x1.8x2 (窗洞)=83.712+ 3.072-4.2-6.48=76.10m²
3.天棚装饰：
(1)天棚抹灰: S= (7.5-0.18) x (6-0.24) =42.16m²
(2)天棚刷乳胶漆: S= (7.5-0.18) x (6-0.24) =42.16m²
