Answer:

192 cm3

Step-by-step explanation:

The volume of any pyramid is 1/3 × b × h, where b =  area of base of the pyramid and h = height of the pyramid.

  • In this case, the dimensions for the base are 6 and 8.
  • The height is 24

Area of Base:

  • \frac{6*8}{2}
  • 48/2
  • 24

Now, we multiply 24 by 24.

  • 24*24
  • 576

Lastly, we divide by 3.

  • 576/3
  • 192

Therefore, the answer is 192 cm^3.
