Can someone help me with Volume pyramids..

Answer:
[tex]\large\boxed{V=\dfrac{125}{3}\ cm^3=41\dfrac{2}{3}\ cm^3}[/tex]
Step-by-step explanation:
The formula of a volume of a pyramid:
[tex]V=\dfrac{1}{3}BH[/tex]
B - area of a base
H - height
We have
[tex]B=5\cdot5=25\ cm^2[/tex]
[tex]H=5\ cm[/tex]
Substitute:
[tex]V=\dfrac{1}{3}(25)(5)=\dfrac{125}{3}=41\dfrac{2}{3}\ cm^3[/tex]
