Answer:
sides are of 16 in
Step-by-step explanation:
here's your solution
==> area of square = 256 in^2. [given]
==> side of square = 4x
==> area of square= side^2
==> 4x^2 = 256
==> 16x^2 = 256
==> x^2 = 256/16
==> x^2 = 16
==> x = √16
==> x = 4
==> x = 4
hence sides are of 16 in

Answer:
n = 1/5
Step-by-step explanation:
Let's solve your equation step-by-step.
5(n−
1
/10
)=
1/
2
Step 1: Simplify both sides of the equation.
5(n−
1
/10
)=
1
/2
(5)(n)+(5)(
−1
/10
)=
1/2
(Distribute)
5n + −1
/2
=
1
/2
Step 2: Add 1/2 to both sides.
5n + −1
/2 + 1
/2 = 1
/2 + 1
/2
5n=1
Step 3: Divide both sides by 5.
5n
/5 = 1

We have the base measurement for the triangles composing the sides. We need their altitude.
Imagine a right triangle with these sides:
(1) from the apex of the pyramid to the point on the base directly underneath it (471 ft);
(2) from the middle of base edge to the point underneath the apex (half of 708 ft = 354 ft);
(3) the hypotenuse, the altitude of a triangular side.
Using the Pythagorean Theorem, we find the hypotenuse to be
√(471^2 + 354^2) = about 589.2 feet
Now we add up the four triangles' areas. Each is base * altitude / 2, so:
4 x 708 x 589.2 / 2
= 2 x 708 x 589.2
= 834,307.2 square feet, the lateral area.
