Question

the formula s=sqrt sa/6 gives the lenth of the side , s, of a cube with a surface area,SA. how much longer is the side of a cube with a surface area of 1,200 square inches than a cube with the surface area of 768 square inches?

Answer 1

A!!!!!

2 sqrt2in

Explanation:

Answer 2

Using the given formula, replace sa with the given surface areas and solve for s:

Surface area = 1200

s = √1200/6

s = √200

s = 14.142

Surface area = 768

s = √768/6

s = √128

s = 11.313

Difference:

14.142 - 11.313 = 2.829 inches

Round answer as needed.
