Answer: Base area would be 12 square feet.
Step-by-step explanation:
Since we have given that
Volume of pyramid = 64 ft³
Height of pyramid = 16 ft
As we know the formula for "Volume of pyramid":
[tex]Volume=\dfrac{1}{3}\times Base\ area\times height\\\\64=\dfrac{1}{3}\times base\ area\times 16\\\\\dfrac{64\times 3}{16}=Base\ area\\\\12\ ft^2=Base\ area[/tex]
Hence, base area would be 12 square feet.
