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

15 cm 2

30 cm 2

3 cm 2

1.5 cm 2

D

Step-by-step explanation:

Let's convert all the side lengths into centimetres to make things easier first.

We already have 4 cm and 2.5 cm, but we need to convert 12 mm into cm. We know that 1 cm = 10 mm, so we have the proportion:

1 cm / 10 mm = x cm / 12 mm, where x is the number of centimetres in 1 millimetre

Cross multiply:

10x = 12

x = 12/10 = 1.2 cm

Now, we need to find the value of B for the triangular prism. B is just the letter denoting the base area, which is a triangle. The base of the triangle is 1.2 cm and the height is 2.5 cm. The area of a triangle is denoted by: , where b is the base and h is the height.

So:

Thus the answer is D.
