Question

A cube has a side length of 10 inches. Jada says the surface area of the cube is

600 in?, and Noah says the surface area of the cube is 3,600 in?. Remember we
calculate surface area by finding the area of all the surfaces and adding them up.
Here is how each of them reasoned:
Jada's Method:
Noah's Method:
6. 102
6.102
6.100
602
600
3,600
Do you agree with either of them? Explain your reasoning.

Answer 1

Jada is correct in this situation.

Step-by-step explanation: Noah's math is not correct. He goes from 6 times 10^2 to 60^2, which you cannot do. You first must do the exponents (10^2=100) and then multiply it by 6. Jada's method should be similar to that.

Answer 2

I agree with Jada

Explanation:

So first you would find the area of one of the faces and it is 100 and then you would multiply the area of one face by 6 because there are 6 faces so you would get 600 inches so Jada would be right
