Question

The formula s = StartRoot StartFraction S A Over 6 EndFraction EndRoot gives the length 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 180 square meters than a cube with the surface area of 120 square meters?

Answer 2

Answer:

(√30 - 2√5) m

Explanation:

s = √S.A/6

Where,

s = sides of a cube

S.A =surface area of a cube

Cube 1: surface area = 180 square meters

s = √(S.A/6)

= √(180/6)

= √30 m

Cube 2: surface area = 120 square meters

s = √(S.A/6)

= √(120/6)

= √20

= 2√5 m

Difference between the sides of the cube = (√30 - 2√5) m
