Question

what is the volume of this triangular pyramid? 5 cm 8 cm 9.9 cm cubic centimeters

Explanation:

Step1: Calculate base area

The base is a triangle with base 8 cm and height 5 cm. Area = $\frac{1}{2} \times 8 \times 5 = 20$ cm².

Step2: Calculate volume

Volume of pyramid = $\frac{1}{3} \times$ base area $\times$ height. Height = 9.9 cm. Volume = $\frac{1}{3} \times 20 \times 9.9 = 66$.

Answer:

66 cubic centimeters
