Question

formula for area of a triangle prism

Answer 1

Step-by-step explanation:

The Surface area of a triangular prism is given as:

$ab + 3bh$

Example: Calculate the surface area of a triangular prism with side 7 cm, base 5 cm and height 6 cm.

Solution:

We know that Surface area of a triangular prism is:

$ab + 3hb$

Given,

a = 7

b = 5

h = 6

Using the formula:

$7 \times 5 + 3 \times 5 \times 6 \: \: 35 + 90$

$= 125$

So, the surface area of the given triangular prism is 125 cm²
