Question

What is the volume of this triangular prism?

Answer 1

Answer:

$V=5,676.16cm^3$

Step-by-step explanation:

The volume of a triangular prism is defined by the formula:

$V=(area-of-base)*(length)$

In this case the base is triangular and the area of a triangle is: $A=\frac{1}{2}(base)*(height)$

Then the volume is:

$V=\frac{1}{2}(base*height*length)$

Now we have to replace with the given values:

$V=\frac{1}{2}(22.4cm*18.1cm*28cm)\\\\V=\frac{1}{2}(11,352.32cm^3)\\\\V=5,676.16cm^3$

Then the correct answer is the third option.

$V=5,676.16cm^3$
