I believe that the answer to the question would be 4.5
The question is incomplete. Here is the complete question:
What is the volume of this triangular prism?
Base length = 22.4 cm
Height = 18.1 cm
Length = 28 cm
A) 313.6 cm3
B) 506.8 cm3
C) 5,676.16 cm3
D) 11,352.32 cm3
Answer:

Step-by-step explanation:
Given:
The base of the prism is triangular with base length equal to 22.4 cm and height 18.1 cm. The length of the prism is 28 cm.
The volume of a triangular prism is defined by the formula:

Here, the base is triangular and the area of a triangle is:

Therefore, the volume of the triangular prism is given as:

Now, plug in the given values and solve for the volume 'V'.

Therefore, the correct answer is the third option.

No at least two side need to be parallel to be that so almost anything will be your answer
Ans given below
-3r-12=-21
-3r=-21+12
-3r=-9
r=-9\-3
r=3
