The equation of an ellipse is x²/a² + y²/b² =1

a being the distance between the center & x intercept =7
b being the distance between the center & y intercept =5

Hence the equation of this ellipse is:

x²/49 + y²/25 =1

Answer:

400 units³

Step-by-step explanation:

The volume (V) of the square pyramid is

V = $\frac{1}{3}$ area of base × height (h)

where h is the perpendicular height.

Consider the right triangle formed by a segment from the vertex to the midpoint of the base and the slant height ( the hypotenuse )

Using Pythagoras' identity on the right triangle

h² + 5² = 13²

h² + 25 = 169 ( subtract 25 from both sides )

h² = 144 ( take the square root of both sides )

h = $\sqrt{144}$ = 12

Area of square base = 10² = 100, hence

V = $\frac{1}{3}$ × 100 × 12 = 4 × 100 = 400
