Option B.
Step-by-step explanation:
A square pyramid has a height = 9 units and volume = 147 unit³
Then By the formula,
Volume of pyramid =
147 =
147 = 3(Area of the base)
Area of the base = unit²
Now we have to find the height of a prism having same area of base and volume as the square pyramid.
Volume of a prism = Area of the base × height
We plug in the values of volume and area of the base
147 = 49×height
Height =
= 3 units
Option B. is the answer.
