Step-by-step explanation:
Volume of a rectangle = [tex]\frac{1}{3}(\text{Area of the rectangular base)(\text{Height})}[/tex]
Area of the rectangular base = Length × Width
= 7 × 8
= 56 square in.
Height of the pyramid = 9 in.
Therefore, Volume of the given pyramid = [tex]\frac{1}{3}(56)(9)[/tex]
= 168 cubic in.
Option (3) will be the correct option.
