The volume and surface area of this square pyramid is approximately 277.33 and 281.6 respectfully.

Step-by-step explanation:

To find the volume of a pyramid, you need to multiply the base area by the vertical height and divide it by 3. In this case, the volume of the square pyramid would be = = ≈ 277.33 . If you want to find the surface area of a shape, you have to calculate the area of every side making up the 3-dimensional figure and add them all together to figure out the surface area. In this case, the surface area would be = = = = 281.6 . So the volume of the square pyramid would be approximately 277.33 , and the surface area is 281.6 .

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.
