Answer 2

○=> Correct answer :

$\color{plum} = \tt\bold{30 \: cubic \: inches}$

○=> Steps to derive correct answer :

Given :

Area of base of a triangular pyramid = 9 inches

Length of height of triangular pyramid = 10 inches

We know that :

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

Which means :

Volume of this triangular pyramid :

$= \tt \frac{1}{3} \times 9 \times 10$

$=\tt \frac{9 \times 10}{3}$

$=\tt \frac{90}{3}$

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

Thus, the volume of this pyramid = 30 inches³
