Volume of a triangular pyramid = 1/3 × base area × height
We have been given base area as 16 square in
Volume of a triangular pyramid = 1/3 × 16 × height
We need to check the options for the expression whose result will give a base area of 16 square in.
From the options:
(8×3)/2 = 12
(11×4)/2 = 22
(16 ×18)/2 = 144
(8 × 4)/2 = 16
1/3 and the height is common to all options. The expression in bracket represent the base area.
Hence, the group that found the volume of triangle pyramid with a base area of 16 square in is
[tex]\frac{1}{3}(\frac{8 ×4}{2})\times q\text{ (option D)}[/tex]
