Given:
Height of the prism = 9 cm
Dimensions of the base triangle are:
height of the triangle = 3 cm
Base length = 4 cm
Required:
Find the area of the triangular prism.
Explanation:
The surface area of the triangular prism is given by the formula:
[tex]A=(Perimeter\text{ of the base}\times length\text{ of the prism\rparen+\lparen2}\times base\text{ area\rparen}[/tex]
Substitute the given values in the formula.
[tex]A=[(4+4+4)\times9]+2(\frac{1}{2}\times4\times3)[/tex][tex][/tex]
