Please help me with this and ill offer u 63 points lol

Answer 1

The volume and surface area of this square pyramid is approximately 277.33
`m^3` and 281.6
`m^2` respectfully.

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
`(8*8*13)/(3)` =
`(64*13)/(3)` =
`(832)/(3)` ≈ 277.33
`m^3`. 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
`(13.6*8)/(2) *4 + 8^2` =
`(108.8)/(2) * 4 + 64` =
`54.4 * 4 + 64` =
`217.6+64` = 281.6
`m^2`. So the volume of the square pyramid would be approximately 277.33
`m^3`, and the surface area is 281.6
`m^2`.
