Volume of solid created =
.
<u>Step-by-step explanation:</u>
We have , A new solid is created by cutting a right rectangular prism from a cube. The right rectangular prism has a length of 5 m, a width of 4 m, and a height of 2 m. The side lengths of the cube are 5 m . Volume of solid created = Volume of cube - Volume of rectangular prism
Volume of cube = 
⇒ 
⇒ 
⇒ 
Volume of rectangular prism = 
⇒ 
⇒ 
⇒ 
Now, Volume of solid created = Volume of cube - Volume of rectangular prism
⇒ Volume of solid created = 
⇒ Volume of solid created = 
⇒ Volume of solid created = 
∴ Volume of solid created =
.
