The surface area of a cube is simply the area of one face multiplied by 6, since all of the 6 faces are exactly the same, therefor:
Surface area = 5*5*6 = 150 ft^2
This is really weird.
-- NONE of the situations matches the equation at the top.
-- And the equation at the top isn't even really any big deal . . .
it's <em>always</em> true, no matter what ' t ' is . If you remove all of
the parentheses and simplify it, it says that 6 = 6. Well duh !
Answer:
d = 6sqrt(2) or 8.4853
Step-by-step explanation:
<u><em>Formula</em></u>
P = 4*s
s^2 + s^2 = d^2 where d is the diagonal and s is the side.
<u><em>Givens</em></u>
P = 24
<u><em>Solution</em></u>
P = 4s Substitute for s
24 = 4*s Divide by 4
24/4 = s
s = 6
================
d^2 = s^2 + s^2
d^2 = 6^2 + 6^2
d^2 = 36 + 26
d^2 = 72
d = sqrt(72)
Factors of 72
72: 6 * 6 * 2
<em><u>Rule</u></em>: Every pair of = factors allows you to take one of them outside the sqrt sign and throw the other a way. If there are no pairs, whatever you started with stays under the root sign.
sqrt(6*6*2) = 6sqrt(2)
- The diagonal length is either
- d = 6*sqrt(2) or
- d = 8.4853
