Math(in English)

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

1.2X1.2X1.2

=1.728

---------------------------------------------------------------------------------

2)2.304X1000000/40/12/100

=4800/100

=48

1) 1.2^3=1.728
So the volume is 1.728cm3

2) 2.304/(40*12)
=0.0048

1. 1.2x1.2x1.2
=1.728
2. 2.304divided by40divided by12
=0.0048
