17. If the perimeter of square 1 is 104 ft and the

Black_prince [1.1K]

Answer:

none of the choices is correct

Step-by-step explanation:

To find the length of the side of square 1, divide the perimeter, 104÷4 = 27

That is the hypotenuse of the triangle.

The square of 27 is 729

Subtract the given square of Square 2, 576

729 - 576 = 153

Take the square root of 153 to find the length of the side of Square 3

√153= 12.37

I hope this helps. It's just a bit more challenging version of Pythagorean Theorem: a² + b² = c²

Suppose the height of the pyramid is 20 yards. What is the pyramid's volume?

DedPeter [7]

Answer : The correct option is, (B) 1500 cubic yards.

Step-by-step explanation :

Formula used to calculate the volume of square pyramid is:

$V=\frac{a^2\times h}{3}$

where,

V = volume of pyramid

a = base edge of pyramid

h = height of pyramid

Given:

Base edge of pyramid = 15 yards

Height of pyramid = 20 yards

Now putting all the given values in the above formula, we get:

$V=\frac{a^2\times h}{3}$

$V=\frac{(15\text{ yrads})^2\times (20\text{ yards})}{3}$

$V=1500\text{ yards}^3$

Therefore, the volume of pyramid is 1500 cubic yards.
