Answer:
The answer to your question is letter A) 144.2 cm³
Step-by-step explanation:
Formula
Volume = Area (base) x height
Process
1.- Find the area of the base (triangle)
Area = [tex]\frac{1}{2} base x height[/tex]
base = 4
height = 7
Area = [tex]\frac{1}{2} 4 x 7[/tex]
Area = 14 cm²
2.- Find the volume
Substitution
Volume = 14 x 10.3
Volume = 144.2 cm³
