Question #a4948

Answer 1

`25000 cm^3`

Explanation:

Let `h,l and t` be the height, length and thickness of the wall.

Volume of wall : `V=h*l*t`

`=>` Volume of Wall1 : `V1=100*50*30`
`=>` Volume of Wall2 : `V2=100*50*25`

`=>` difference between the volume of two walls :
`= V1-V2=100*50*(30-25)=100*50*5=25,000 cm^3`
