Can anyone help me ill metal & fan.

3. anonymous

do you know the equation to find volume? and the one for surface area?

4. anonymous

Surface area is A; 1176ft. :

5. anonymous

voluam is 1512ft.

6. anonymous

ok so the surface area to volume ratio is 1176/1512. Is that less than 1?

7. anonymous

put surface area over volume in a fraction and if the fraction is greater than 1 then he shouldn't manufacture them but in this case it is less than 1 so he should manufacture them.

8. anonymous

no it isnt less then one i dont think @peachpi

9. anonymous

don't guess, just stick it in a calculator

10. anonymous

1176/1512 = 0.7777777....

11. anonymous

woops, sorry. it is less then one.

12. anonymous

so then they would make the box

13. anonymous

is 1176 less than 1512? it is. if the numerator of a fraction is less than the denominator, isn't it less than 1? it is. so it is less than 1

14. anonymous

Could you help me with another one please? @peachpi

15. anonymous

sure

Three identical cubes are put together to form a square prism. The volume of each cube is 125 cubic centimeters. Find the volume of the prism & Find the surface area of the prism?

17. anonymous

@peachpi @night.soul45

18. anonymous

the volume is 375 cubic centimeters

19. anonymous

can you show me how you got 375?

20. anonymous

if all have a volume of 125 then you multiply that by the number of cubes

21. anonymous

22. anonymous

first i have to find the length of 1 of the sides of a cube

23. anonymous

okay

24. anonymous

the surface area is 350 centimeters

26. anonymous

Can you help me with a few more ?

27. anonymous

sure

A short fence will be built around the perimeter of the garden region. Find the number of meters of fencing required. Round your answer to the nearest tenth. Show all your work.

@night.soul45 ????

perimeter of the curve of the semicircle$P=\frac{ 3.14 }{ d }$ in which the diameter is 1.2 meters. that would equal 2.62 now to find the whole perimeter$(1.8\times2)+1.2+2.62=7.42$ which rounds to 7.4meters.

Im so sorry i had to go pick up my baby cousin!
