2 wide walls (15x6)x2=180 square feet
2 long walls (25x6)x2=300 square feet
ground 25x15=375 square feet
sum them all up and you get
375+300+180=855
you need paint for 855 square feet
Answer:
The answer should be 12 1/2.
Step-by-step explanation:
If not let me know. If so, brainliest??
24 sponge fingers and 420 jelly
Answer:
D) 30
Step-by-step explanation:
L and V are the same so you have to rotate triangle LMN so that L points up like V. Next look at the hypotenuses, they are 40 and 24. set them up it a proportion like so 40/24. Then simplify to get 5/3. Now you multiply that by 18 to find the missing side with is 30.
If you can make my answer the brainliest that would be much appreciated. Thanks!
Answer:
Step-by-step explanation:For any shape it’s always true that for volume
V
the surface area is: =2‾‾‾√3
for some constant depending on the shape. So to work out the surface area from the volume we just need to know the value of for the shape in the question.
For a cube for example we have that =6, assuming consistent units i.e.: unit 2 for area and unit 3
3
for volume.
More generally if we have formula for both volume and surface area in terms of a particular one dimensional measurement
d
of the shape then we can always write these formula in the form:
=13
=12
for constants constants 1 and 1
. Then we have:
=1‾‾‾√3
=1(1)2‾‾‾‾‾‾√3
=121‾‾‾√32‾‾‾√3
and therefore:
=121‾‾‾√3
For example for a sphere we have that that =42 and =433 and therefore:
=4(43)2‾‾‾‾‾‾√3
=36‾‾‾‾√3
So if a particular sphere has volume =8 then we can calculate its surface area to be:
=36‾‾‾‾√382‾‾√3=436‾‾‾‾√3 m2
