Answer:

1. V= L×W×H

V= 12cm×12cm

V= 1728cu.cm

2. V= L×W×H

V= 24cm×3cm

V= 432cu.cm

3. V= LxWxH

V= 2mX2m

V= 20cu.m

4. V= L×W×H

V= 20×10

V=4000cu.cm

Step-by-step explanation:

To answer it

You need to times(multiplication) the given numbers of Length and width

For example of number 3:

The length is 2m and the width is 2m

Answer is 4

After you did that your going to times 4×5

The answer is 20

So, The finals answer is:

20cu.cm

If you want your teacher to know that your really solving write the solution at the back

If you dont know what cu.cm stands for. cu stands for Cubics you could also write cm³

The 3 stands for Cubics(cu)
