Question

What is the value of B for the following triangular prism?

Answer 1

Answer:

A. $5.25\text{ cm}^2$

Step-by-step explanation:

We have been given an triangular prism. We are asked to find the value of B for our given prism.

$\text{Volume of triangular prism}=B\times h$, where,

B = Area of base,

h = Height of prism.

The value of B for our given prism would be the area of base. Upon looking at our given prism, we can see that base of our given prism is triangular, so we will use area of triangle to find the value of B.

1 mm = 0.1 cm

28 mm = 2.8 cm

$\text{Area of triangle}=\frac{1}{2}(\text{Base}\times \text{Height})$

$\text{Area of triangle}=\frac{1}{2}(\text{2.8 cm}\times \text{3.75 cm})$

$\text{Area of triangle}=\frac{1}{2}(10.5\text{ cm}^2)$

$\text{Area of triangle}=5.25\text{ cm}^2$

Therefore, the value of B is 5.25 square centimeters and option A is the correct choice.
