○=> Correct answer :

Given :

Area of base of a triangular pyramid = 9 inches

Length of height of triangular pyramid = 10 inches

We know that :

$\tt \: \color{hotpink}volume\: of \: a \: triangular \: pyramid \color{plum}= (1)/(3) Bh$

Which means :

Volume of this triangular pyramid :

$= \tt (1)/(3) * 9 * 10$

$=\tt (9 * 10)/(3)$

$=\tt (90)/(3)$

$\color{plum} =\tt 30 \: {inches}^(3)$

Thus, the volume of this pyramid = 30 inches³
