Answer:
V = 330 ![in^{3}](https://tex.z-dn.net/?f=in%5E%7B3%7D)
Step-by-step explanation:
To find the volume of a pyramid use this equation:
![V = \frac{lwh}{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7Blwh%7D%7B3%7D)
l = length
w = width
h = height
Lets assign each of these variables to what is in the picture:
l = 18 in
w = 5 in
h = 11 in
Now, plug these into the equation and solve:
![V = \frac{(18)(5)(11)}{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B%2818%29%285%29%2811%29%7D%7B3%7D)
Distribute the numerator
V = 330 ![in^{3}](https://tex.z-dn.net/?f=in%5E%7B3%7D)
Thus, the exact volume of the pyramid is 330
.
Hope this helps!!
