Answer: [tex]V=20h^{2}[/tex]
Step-by-step explanation:
1. The formula for calculate the volume of a rectangular prism is:
[tex]V=L*w*h[/tex]
Where L is the lenght, w is the width and h is the height.
2. Based on the information given in the problem:
Length=L=10
width=w=[tex]2h[/tex]
height=[tex]h[/tex]
3. Then, you can write the following expression:
[tex]V=(10)(2h)(h)[/tex]
[tex]V=10(2h^{2})\\V=20h^{2}[/tex]
