The volume v of a pyramid with a square base with side length s and height h is upper v equals one third s squared hv= 1 3s2h. s

zheka24 [161]

In this question,it is given that,

The volume v of a pyramid with a square base with side length s and height h is

$V = \frac{1}{3} s^2 h$

And we have to solve for s.

First we will get rid of 3 by multiplying both sides by 3, that is

$3V = s^2h
\\
s^2 = \frac{3V}{h}
\\ s = \sqrt{ \frac{3V}{h}}$

And in the next part it is given that , volume is 7700 cubic meters and height is 148 meters .

Substituting these values, we will get

$s = \sqrt{ \frac{3V}{h}}
\\
s = \sqrt{ \frac{3*7700}{148}} = 12.5 meters$

Can someone fr help me with this like right now i’ll appreciate it sm

Step-by-step explanation:

Since

$\frac{108}{72} = \frac{3}{2}$

$\frac{72}{48} = \frac{3}{2}$

$\frac{48}{32} = \frac{3}{2}$

The function has a constant factor so we have a exponential function.

The equation of a exponential function is

$y = a(b) {}^{x}$

Where a is the initial value and b is the growth factor

The growth factor is 3/2,

The initial value in 32

$y = 32 ( \frac{3}{2} ) {}^{x}$

Plug in 4 for x.

You will get 162

Plug in 5 for x you will get

243.
