Answer:

Part A-      Surface area = 150cm squared

Step-by-step explanation:

First you find the area of one side of the cube-

side length (5) x side length (5) = area (25)

25 is the area of one side of the cube.

Then you multiple the area of one side (25) by the amount of sides that there are (6)-

25 x 6 = 150

The area of a rectangle is simply length * width.  Thus, simply multiply them, and FOIL.

3x ^2 + 3x - 5x - 5

Combine like terms

Hope it helps :) and let me know if you want me to elaborate.

Why doesn't a cube root have two answers
user100 [1]

A cube root has THREE answers !

Unfortunately, two of them are 'complex' numbers, which involve
'imaginary' numbers', and those involve the square root of -1 . 
In Middle School, you're not equipped to go there yet. 

Just hang on for a few more years.  You'll learn all kinds of
beautiful things in math, more than you can imagine now.
You'll learn that whatever number the root is, there are
THAT many answers.

Like for example, if you want the 7th root of a number,
there are seven of them !
