The volume in a pyramid is given by the next formula:
[tex]V=\frac{A_b\cdot h}{3}[/tex]
Where:
Ab is the area of the base
h is the heigh of the pyramid.
The area of the base is:
[tex]A_b=l\cdot w[/tex]
where l is length and w is the width
l=49cm
w=36cm
[tex]A_b=49\operatorname{cm}\cdot36\operatorname{cm}=1764\operatorname{cm}^2[/tex]
Then, the volume of the figue is:
[tex]V=14700\operatorname{cm}^3[/tex]
