Here is a picture of a cube, and the net of this cube.What is the surface area of this cube?
2 answers:
The surface area of the net of cube is 726 sq cm
The surface area of the cube is 484 sq cm
Step-by-step explanation:
Here we need to find out the surface area of net of a cube and a cube
Given,
Each side of the cube is 11 cm
The net of a cube consists of 6 squares.
Formula
The surface area of the net of the cube = 6 X ( area of each square)
= 6 X ( 11 X 11) sq cm
= 726 sq cm
Now, the surface area of a cube = lateral surface area of the cube
Formula
The lateral surface area of the cube = 4 X
= 4 X sq cm
= 484 sq cm
Hence the surface area of the net of a cube and only a cube is different.

For this problem, we are going to use the Remainder Theorem. This says that for to be a factor of a polynomial
, then
. Essentially, it says that
is a factor if when you substitute
into the polynomial you get a result of 0.
Thus, in our case, when we substitute into the polynomial, we should get an answer of 0 if
is a factor of the polynomial. Given this information, we can solve for
:
The solution is c = 3.
