Question

What is the value of B for the following triangular prism? Remember that there are 10 millimeters in a centimeter.

Answer 1

Answer:

For B, do you mean the area of the base of the triangular prism?

If this is the case, then:

$B=1.5cm^2=15mm^2$

Step-by-step explanation:

As you can see, the base of a triangular prism is basically a triangle. So, if you need to find the area of its base you can calculate it using the formula for the triangle area, which is given by:

$A=\frac{b*h}{2}$

Before going any further we need to do a conversion in order to work with the same units:

$12mm*\frac{1cm}{10mm} =1.2cm$

Now, the value of B is given by:

$B=A=\frac{1.2*2.5}{2} =1.5cm^2=15mm^2$

Answer 2

Step-by-step explanation:

I actually earned :

1.2 * 2.5=3

3 divid by 2=1.5

1.5 * 4=60
