Question

what is the volume of this triangular pyramid? 5 mm 6 mm 9 mm cubic millimeters submit

Explanation:

Step1: Calculate base area

The base is a triangle with base 9 mm and height 4 mm. Area = $\frac{1}{2} \times 9 \times 4 = 18$ mm².

Step2: Calculate pyramid volume

Volume = $\frac{1}{3} \times$ base area $\times$ height (5 mm). Volume = $\frac{1}{3} \times 18 \times 5 = 30$.

Answer:

30 cubic millimeters
