Answer:
4.41
Step-by-step explanation:
Use the definition of square:
Hence,
Multiply 2.1 by 2.1 using column multiplication (or using calculator):
so
The area of cardboard she used is given by the formula A = , where s represents the side length of the cube.
Now the question asks for the equation , which we can use to solve for s
it means
we have to solve for s
or in other words we have to isolate s
Now
A=
Divide both sides by 6
or
Take square root on both side
So this is the formula we can use to solve for s
