Answer :
Answer:
The volume of a pyramid is 1243.5 cubic inches.
Step-by-step explanation:
Given : A pyramid with a square base, where the side length of the base is 18.5 in and the height of the pyramid is 10.9 in.
To find : The volume of a pyramid ?
Solution :
The volume of the pyramid is [tex]V=\frac{1}{3}a^2 h[/tex]
Where, a=18.5 in. is the side length of the base
h=10.9 in. is the height of the pyramid.
Substitute the value,
[tex]V=\frac{1}{3}\times (18.5)^2\times 10.9[/tex]
[tex]V=\frac{1}{3}\times342.25\times 10.9[/tex]
[tex]V=1243.50\ in^3[/tex]
Therefore, the volume of a pyramid is 1243.5 cubic inches.
