Find the surface area of the right prism with the given features: A right triangle with legs of length 12 a base of length 9 and height equals 23.

Answer 1

I assume the prism has a triangular base and a height of 23.

A right triangle with legs of length 12 has sides 12,12,12√2

so, where does the 9 come in?

Do you mean a right triangle with legs of length 9 and 12, and thus a hypotenuse of 15?

If so, then add up the areas of
two triangles, each 1/2 x 9x12
three rectangles with dimensions
9x23, 12x23, 15x23

Answer 2

Yes Steve. Triangular base. She just said leg lengths of 12, a base of 9, and height of 23.
