Answer:

1,982 ft³

Step-by-step explanation:

Solving

Volume of rectangular prism (below)

lbh
12 x 12 x 12
144 x 12
1728 ft³

Volume of square pyramid

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

Total Volume : 1728 + 253.92 = 1,981.92 ft³ ≅ 1,982 ft³

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) )

Can you exchange the coordinates of points ( x 1, y 1) and ( x 2, y 2) in the distance formula and still find the correct distan

notka56 [123]

Answer:

yes

Step-by-step explanation:

As an example

(x₁, y₁ ) = (1,2) and (x₂, y₂ ) = (5,3), then

d = $\sqrt{(5-1)^2+(3-2)^2}$ = $\sqrt{4^2+1^2}$ = $\sqrt{16+1}$ = $\sqrt{17}$

Now let (x₁, y₁ ) = (5,3) and (x₂, y₂ ) = (1,2), then

d = $\sqrt{(1-5)^2+(2-3)^2}$ = $\sqrt{(-4)^2+(-1)^2}$ = $\sqrt{16+1}$ = $\sqrt{17}$
