The surface area of the triangular prism is of 140 cm².
<h3>What is the surface area of a prism?</h3>
It is the sum of the areas of all faces of a prism. In this problem, the prism has these following faces:
- One rectangle of dimensions 8 cm and 6 + 4 + 5 = 15 cm.
- Two right triangles with sides 4 cm and 5 cm.
For a rectangle, the area is given by the multiplication of the dimensions, hence:
Ar = 8 x 15 = 120 cm²
For each right triangle, the area is given by half the multiplication of the sides, hence:
At = 2 x 0.5 x 4 x 5 = 20 cm².
Then the surface area of the prism is:
S = 120 cm² + 20 cm² = 140 cm².

Answer:Domain = R - {3}
R = set of real numbers
Step-by-step explanation:
Domain cant be that number which when put into function gives undefined value. :. in 5/(x-3) , x-3 != 0.
:. we can put any real number in the function to get a value but not 3.HOPES THIS HELP IF YOU HAVE ANY MORE QUESTION JUST COMMENT.
