Answer:
The correct answer is third option
36x²
Step-by-step explanation:
It is given a prism with base area 3x²
To find the height of the prism
From the figure we get the height 'h' of the prism
h² = 13² - 5²
= 169 - 25
= 144
h = √144 = 12
To find the volume of prism
Volume of prism = Base area * Height
= 3x² * 12
= 36x²
