Hello!
For this you can plug in the x values in the choices and see if you get the y value
y =
-4^3 is -64
when you subtract a negative you are just adding
-64 + 4 = 60
Then you do the second one
-3^3 is -27
-27 + 3 is -24
Then the third one
-2^3 is -8
-8 + 2 is -6
Then the last one
-1^3 is -1
-1 + 1 = 0
Since we did not get -2 the answer is D
Hope this Helps!

Answer: Surface area is equal to 200
Volume is equal to 333.33
Step-by-step explanation:
First, let's do surface area.
The surface area of a pyramid is equal to 1/2(perimeter of base)(lateral height) + area of the base
The perimeter of the base is 10(4) = 40; as the base is a square with a side length of 10.
The lateral height is given as 5 cm.
The area of the base is 10(10) = 100.
We can plug those numbers into the equation to get 1/2(40)(5) + 100, which comes out to be 200.
Now for volume.
The volume of a pyramid is equal to 1/3(area of the base)(height).
We already have the area of the base, which is 100.
The height is given as 10 cm.
Plugging those numbers into the equation, we get 1/3(100)(10), which is 1000/3 or about 333.33.
Hope this helps!
