Answer 1

Given:

A triangular prism with base sides 3cm, 8cm and height 12cm.

To find:

Find the lateral surface area of the triangular prism.

Explanation:

Lateral surface area of triangular prism

$=(a+b+c)h$

Where, a, b, c are base sides and h is the height.

Solution:

We will use three sides and height as:

$\begin{gathered} A=(a+b+c)h \\ A=(3+3+8)\times12 \\ A=168 \end{gathered}$

Hence, this is the required lateral area of triangular prism.
