help

parthkohli · Answer

You use the distributive property

mathslover · Answer

two properties used: 
$$\large{(a\pm b)^2=a^2\pm 2ab+b^2}$$
$$\large{\color{red}{a(b \pm c)=ab \pm ac}}$$

parthkohli · Answer

That comes down to just one property.$$a(b\pm c) = ab\pm ac$$

mathslover · Answer

right 

derivation

anonymous · Answer

ok

anonymous · Answer

take the cubed root, square that and then multiply by 6. In this case the answer is 294 yards sq.

Edit:

LOL. I got a thumbs down! I must have pissed off the first guy for giving him thumbs down for providing a wrong answer.

A cube has equal height, length and width. 7*7*7=343. Since the surface area is length * width * the number of sides, in this case the SA is 7*7*6=294.
