Find the volume of the square pyramid to the nearest cubic unit. edge 10 ft; height 11 ft 1,467 ft3 1,100 ft3 550 ft3 367 ft3

We know that
[volume of square pyramid]=(1/3)*b²*h
where
b is the length side of the square base> 10 ft
h is the height> 11 ft
[volume of square pyramid]=(1/3)*10²*11> 366.67 ft³> 367 ft³

the answer is
367 ft³

B? ? i'm most likely wrong but i think it would be b
