What is the surface area, in square inchis, of a prism with a length of 12 inches a width of 9 inches and a height of 2 inches

The surface area would be 216 square inches because 9 times 12 times 2 is 216. To find volume, you multiply length times width times height to get your answer.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
