Fast i will mark brainliest and give 15 ! which of the following best describes the volume of a pyramid?

one-third of the product of the height and base
one-third of the product of the height and base area
one-third the sum of the height and base area
one-third the sum of the height and base

The second choice.  One-third of the product of the height and base area

Step-by-step explanation:

The formula for volume of a pyramid is

V = (1/3)Bh,  where V is the volume, B is the area of the base, and h is the height.

Translated to English the formula says

"Volume is one-third the product of the base area and the height"

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
