Answer: B. 3388 units³
Explanation:
To find the area of a pyramid, we use the formular;
v = 1/3 Ah
A == area of the base
h = height
h = 84 (from the diagram provided)
we need to calculate the area
area = l × b
 =11 × 11
 =121
v = 1/3 Ah
 = 1/3 × 121 × 84
 =10164/3
 = 3388
Therefore the volume of the pyramid is 3388 units³
