Find the volume of a pyramid with a square base, where the perimeter of the base is 19.9 in and the height of the pyramid is 14.3 in. Round your answer to the nearest
tenth of a cubic inch.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

my dear correct answer is option number 3

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
