A cube has a surface area of 294 square cm. Find the length of one side.
Answers
Where s is the length of the side of the cube.
6s² = 294
s² = 294/6
s² = 49
√s² = √49
s = 7
Length of one side = 7 cm.
I hope this helps.
SURFACE AREA OF CUBE = A = 6*S^2.......WHERE S= SIDE OF THE CUBE
VOLUME OF CUBE = V = S^3
6S^2=294 SQ.CM.
S^2=294/6 = 49 = 7*7
S=7
V = 7^3 = 343 CU.CM.
--hope this helps.

What is a saving account?
A savings account is a basic type of financial product that allows you to deposit your money and typically earn a modest amount of interest. These accounts are federally insured up to $250,000 per account owner and offer a safe place to put your money while earning interest.
Given that, Ann is opening a new savings account with an initial deposit of $250, we need to find the combination of a deposit and a withdrawal will result in a zero balance in Ann's account,
So, if Ann deposit $20 in first week the account balance = 250+20 = $270
Now, since the amount in her account is $270, so to make it zero, she should withdraw all the amount i.e. $270
Hence, the combination of a deposit and a withdrawal will result in a zero balance in Ann's account is
A) Deposit $20 in the first week and withdraw $270 in the second week.
