Answer:
Double
Explanation:
[tex]\text{Volume of a Pyramid=}\frac{1}{3}\times Base\text{ Area}\times Altitude[/tex]
If the area of the base remains the same and the altitude is doubled, we have:
[tex]\begin{gathered} New\; Volume=\frac{1}{3}\times\text{Base Area}\times(2\times Altitude) \\ =2\times(\frac{1}{3}\times\text{Base Area}\times Altitude) \\ =2\times\text{Old Volume} \end{gathered}[/tex]
Thus, if the area of the base remains the same and the altitude is doubled, the volume will double,
