The correct answer would be D. 50m^3
To solve for the volume of the square pyramid you can use the formula for a square pyramid’s volume , V=1/3B.h
B= the base, in those case it is a square so you would use 5 x 5 or 5^2
h=6
Plug the numbers in for the variables to get
V=1/3 5^2 x 6
Which gives you a total of 50 m^3 :)
