The surface area of a solid is just the total area of all its faces. We know a cube has 6 identical faces with area s^2 where s is the side length.
So 6s^2 is the surface area. We can use this to find s.
6s^2 = 600
s^2 = 100
s = 10 cm
4x - 5y = 40
4x = 40 + 5y
x = 10 + 5/4y
The x intercept is 10.
we need help? can somebody answer this question
If you notice the picture below, the amount of fencing, or perimeter, that will be used will be 3w + 2l
now

solve for "w", to see what critical points you get, and then run a first-derivative test on them, for the minimum
notice the

so. you can pretty much skip that one, though is a valid critical point, the width can't clearly be 0
so.. check the critical points on the other
Answer:
Step-by-step explanation:
You need to find the HCF of 36 and 90.
<u>Prime factors of each:</u>
<u>HCF includes all prime factors of both numbers:</u>
- HCF(36, 90) = 2*2*3*3*5 = 180
