Question 9
Find the volume.

Answer:
volume of the triangular pyramid=1/3×base×height
=1/3×(1/2×6×5)×10
=1/3×15×10
=50 yd³
[tex]V = \frac{1}{3} (\frac{1}{2}\times base \: area) \: \times height[/tex]
[tex]V = \frac{1}{3} ( \frac{1}{2}\times base \: area) \: \times height \\ V = \frac{1}{3} (\frac{1}{2} (6)(5))(10) \\ V = \frac{1}{3} (150) \\ V = 50 {yd}^{3} [/tex]
[tex]D. \: \: V = 50 \: {yd}^{3} [/tex]
