of the figure below:
Ilm
Hm
105 m
D Gina Wilson (All Things Algebra), 2014
175m

Answer 1

Area of base

• 1/2BH
• 1/2(10.5)(14)
• 1/2(147)
• 73.5m²

Volume

Area of base×Height

• 73.5(11)
• 808.5m³

Answer 2

808.5 m³

Explanation:

Volume of a Triangular Prism :

Volume = 1/2 × b × h × l

=============================================================

Given :

⇒ b = 11 m

⇒ h = 10.5 m

⇒ l = 14 m

===========================================================

Solving :

⇒ V = 1/2 × 11 × 10.5 × 14

⇒ V = 7 × 115.5

⇒ V = 808.5 m³
