Answer : The correct option is, (B) 1500 cubic yards.
Step-by-step explanation :
Formula used to calculate the volume of square pyramid is:
[tex]V=\frac{a^2\times h}{3}[/tex]
where,
V = volume of pyramid
a = base edge of pyramid
h = height of pyramid
Given:
Base edge of pyramid = 15 yards
Height of pyramid = 20 yards
Now putting all the given values in the above formula, we get:
[tex]V=\frac{a^2\times h}{3}[/tex]
[tex]V=\frac{(15\text{ yrads})^2\times (20\text{ yards})}{3}[/tex]
[tex]V=1500\text{ yards}^3[/tex]
Therefore, the volume of pyramid is 1500 cubic yards.
