《2025年计算全能五年级数学下册人教版》

一、填空题。
$3500\ mL = (\ \ \ \ \ )L$ $1\ L = (\ \ \ \ \ )dm^3$
$1000\ mL = (\ \ \ \ \ )cm^3$ $5000\ dm^3 = (\ \ \ \ \ )m^3$
$6.5\ dm^3 = (\ \ \ \ \ )L = (\ \ \ \ \ )mL$ $1080\ cm^3 = (\ \ \ \ \ )mL = (\ \ \ \ \ )L$
$36.5\ L = (\ \ \ \ \ )dm^3 = (\ \ \ \ \ )cm^3$ $0.0018\ m^3 = (\ \ \ \ \ )cm^3 = (\ \ \ \ \ )mL$

答案： 3.5 1 1000 5 6.5 6500 1080 1.08 36.5 36500 1800 1800

二、下面各题算的对吗？对的画“√”，错的画“×”并改正。
1. $50.4×1.9 - 1.8$
$= 50.4×0.1$
$= 5.04$
$(\ \ \ \ \ )$
2. $67.8÷12.5×0.8$
$= 67.8÷(12.5×0.8)$
$= 67.8÷10$
$= 6.78$
$(\ \ \ \ \ )$

答案：

三、在下面的表格里填上合适的数。
| | 长/cm | 宽/cm | 高/cm | 棱长/cm | 底面积/cm² | 表面积/cm² | 体积/cm³ |
| --- | --- | --- | --- | --- | --- | --- | --- |
| 长方体 | 9 | 6 | 4 | | | | |
| | 10 | 8 | | | | | 1600 |
| | | 40 | 3 | | 2000 | | |
| | 2 | | 1.5 | | 4 | | |
| 正方体 | 6 | | | | 48 | | |

答案： （从上到下） 76 54 228 216 20 152 80 880 50 372 4540 6000 2 22 20 6 6 6 72 36 216 216 4 4 4 16 96 64

四、直接写出得数。
$4.03 - 0.3 =$ $0.2÷0.4 =$ $0.9×7 + 10.7 =$
$4.8×50 =$ $7.2 - 2.7 =$ $(4.8 - 3.6)×5 =$
$0.96÷0.4 =$ $8 + 1.25 =$ $4.9 + 8.7 + 5.1 =$
$6.3 - 3.6 =$ $0.12×2.5 =$ $(10.8 - 0.8)÷2 =$
$6.3÷0.7 =$ $1.08×0.3 =$ $1÷0.125 - 0.875 =$
$75 + 7.5 =$ $4.2 - 1.9 =$ $4.8×0.2×0.5 =$
$0.49 + 0.7 =$ $2.4÷0.06 =$ $1.4 - 0.4×2 =$

答案： 3.73 0.5 17 240 4.5 6 2.4 9.25 18.7 2.7 0.3 5 9 0.324 7.125 82.5 2.3 0.48 1.19 40 0.6
