If you are looking for the height of a pyramid and the volume is 18,069,333.33333 and the length and width are both 440 what is

makkiz [27]

Answer:

h=123,200

Step-by-step explanation:

First you must in the formula for the pyramid, which is

$v=\frac{wlh}{3}$

and as far as the question has gave us

V=18069333.33333

LW=440

1.) Plug those numbers into the the equation, which should be:

$(18,069,333.33333)= \frac{(440)h}{3}$

2.) Then isolate the "h" by dividing both sides by $\frac{440}{3}$ , or multiplying its reciprocal, which is $\frac{3}{440}$

$(\frac{3}{440}) 18,069,333.33333=\frac{440h}{3} (\frac{3}{440} )$

3.) Simplify or round the numbers if you need to.

$h= 123,200$
