Answer
Option C is correct.
Volume of the triangular prism = 49 ft³
Step-by-step explanation
The volume of any prism is given as
Volume of the prism
= (Area of the base or face that is seperated by a perpendicular distance) × (Perpendicular distance between the faces)
For this triangular prism, the base or face is a triangle.
Area of the base or face that is seperated by a perpendicular distance
= Area of a triangle
= ½ (Base) (Height)
= ½ (4) (3.5)
= 7 ft²
Perpendicular distance between the faces = 7 ft
Volume of the prism
= (Area of the base or face that is seperated by a perpendicular distance) × (Perpendicular distance between the faces)
= 7 × 7
= 49 ft³
Hope this Helps!!!
