<span>The formula for the surface area of a triangular prism is SA = bh + (s1 + s2 + s3)H. In this formula, "b" is the triangle base, "h" is the triangle height, "s1," "s2" and "s3" are the three triangle sides, and "H" is the length of the prism.
Hope it works! </span>
The answer is the one that has a denominator of X-5 :)
A function is something that lets you work out what something is depending a variable
e.g: x = y + 5
this function states that the unknown x is equal to whatever the variable y is plus 5
Add up all the sides is one way I think and then try to find the volume like add them all up then divide them by 2
