<u>Volume of square pyramid</u>

  • 1/3Bh
  • 1/3 x 144 x √28
  • 48 x 5.29
  • 253.92

Answer:

1982  ft^3    ( rounded)

Step-by-step explanation:

The cube bottom is   12 x 12 x 12  = 1728

The pyramid top is  1/3 ( 12*12) * sqrt 28 = 253.99

added together = ~ 1982  

( you have to use the HEIGHT of the pyramid for the volume calculation      V = 1/3 *  base area * height        height = sqrt (28)  )

s2008m [1.1K]

Answer:

Slope = \frac{-1}{3}

Step-by-step explanation:

(x₁ , y₁) = (-9 , -4)   & (x₂ ,y₂) = (-3, -6)

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

         = \frac{-6-[-4]}{-3-[-9]}\\\\= \frac{-6+4}{-3+9}\\\\= \frac{-2}{6}\\\\= \frac{-1}{3}
