A written explanation solving the question how much fluid is needed using the Pythagorean method and finding the area of the tri

Alecsey [184]

Answer:

793 liters of washing fluid is needed

Step-by-step explanation:

step 1

Find the slant height of the triangular faces of pyramid

we know that

The lateral area of a square pyramid is equal to the area of its four triangular faces

so

$LA=4[\frac{1}{2}bl]$

where

b is the base of triangle (is the same that the length of the square base)

l is the slant height

To find out the slant height we need to apply the Pythagorean Theorem

so

$l^2=(b/2)^2+h^2$

we have

$b=35.42\ m$

$h=21.64\ m$

substitute

$l^2=(35.42/2)^2+21.64^2$

$l^2=781.9337$

$l=27.96\ m$

step 2

Find the lateral area of the pyramid

$LA=4[\frac{1}{2}bl]$

we have

$l=27.96\ m$

$b=35.42\ m$

substitute

$LA=4[\frac{1}{2}(35.42)(27.96)]$

$LA=1,980.6864\ m^2$

step 3

Find out how much window washing fluid is needed

we know that

2 L of washing fluid cover 5 square meters

so

using proportion

$\frac{2}{5}\ \frac{L}{m^2}=\frac{x}{1,980.6864}\ \frac{L}{m^2}\\\\x=1,980.6864(2)/5\\\\x= 792.27\ L$

Round up

793 liters of washing fluid is needed

a jug holds 4 quarts How many liters of milk dose the jug hold ? round your answer to the nearest hundredth of a liter 1 L=1.06

svetoff [14.1K]

Answer:

Please read the explanation to clarify.

Step-by-step explanation:

What you would have to do is multiply 1.06 by 4 to get 4.24. However, if you search up the exact conversion on g00gle, "how many liters are in 4 quarts?", you get the exact number of 3.78541, which can be rounded to 3.78. I believe if this is more of an exam thing, you should go with the first answer I gave, 4.24, and show how you multiplied to show your work. However, if you would like to use the second answer, it is completely up to you. Either way, I hope this helped, and if you have any further questions please don't hesitate to let me know. :)
