✔ 最佳答案
1. Each side of a cube is 1.2 cm long. Find its volume.ANS:
volume=(1.2)^3
=1.728cm^3
2. The volume of a box is 2.304 m3. It is 40 cm long and 12 cm wide. Find its height in metre.
Ans:
40cm=0.4m
12cm=0.12m
Let h be the height
0.4x0.12xh=2.304
h=48m

1) 1.2^3=1.728
So the volume is 1.728cm3
2) 2.304/(40*12)
=0.0048
So the volume is 1.728cm3
2) 2.304/(40*12)
=0.0048
