Suppose you slice through a square pyramid such that the plane is parallel to the base and halfway up the total height of the pyramid. How does the Side length of the cross-section compared to the side length of the base?

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
