The pyramid shown has a square base that is 24 inches on each side. the slant height is 20 inches. what is the surface area of the pyramid?

Surface area of pyramid = 1536 square inches.

Step-by-step explanation:

Surface area of a pyramid with the square base will be = surface area of base + 4× slant surfaces of the pyramid

area of square base = 24×24 = 576 inches²

area of one slant side of pyramid = (1/2)×side × slant height = (24×20)/2 = 240 square inches

Therefore surface area of complete pyramid = 4×area of slant side + surface area of square base = 4×240 + 576 = 960 + 576 = 1536 square inch.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
