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?

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.

46.2+112.3

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
