Answer:

A = 179.4units²

Step-by-step explanation:

To find the surface area of a square pyramid use this formula

A = a² + 2a√[tex]\frac{a^{2} }{4}[/tex] + h²

So plug in your numbers

  • A = 8² + 2 × 8 ×√[tex]\frac{8^{2} }{4}[/tex] + 6² ≅ 179.37764
  • Round to the nearest tenth

A = 179.4units²

Answer:

160 units^2

Step-by-step explanation:

Base area = 8x8 = 64

   FOUR sides 4 * 1/2 (6)(8) = 96       total  64 + 96 = 160 units^2
