Question

Two cubes have their volumes in the ratio 8:125. What is the ratio of their surface area
​

Answer 1

Answer:

i hope it helps you

Step-by-step explanation:

Let the sides of the cubes be a1 and a2 Ratio of their volumes = (a1/a2)^3 =(8/125) =(2/5)^3 a1/a2 = 2/5-------(1) Ratio of surface areas =(a1/a2)^2 =(2/5)^2 =(4/25) =4:25

Answer 2

Answer:

volume of a cube having side length l, is given by l^3

then L1^3= 8

hence L1 = 2

again L2^3= 125

hence L2=5

and the surface area of the cube is given by 6L^2

hence for L1

= 6(2×2)

= 24

for L2,

= 6(5×5)

= 150

hence there ratio is

24:150
