Question

what is the volume of this triangular pyramid? 14 mm 13 mm 9 mm cubic millimeters submit

Explanation:

Step1: Calculate base area

The base is a triangle with base 9 mm and height 13 mm. Area formula: $\frac{1}{2} \times base \times height$.
$\frac{1}{2} \times 9 \times 13 = 58.5$ mm²

Step2: Calculate pyramid volume

Volume formula: $\frac{1}{3} \times base\ area \times height$ (pyramid height = 14 mm).
$\frac{1}{3} \times 58.5 \times 14 = 273$

Answer:

273 cubic millimeters
