Question

two cubes have there vopume in the ratio of 1:27 find the ratio of their surface area

Answer 1

Answer:

1:9

Step-by-step explanation:

Let their edges be a and b. Then,

  a³/b³ = 1/27 (or) (a/b)3 = (1/3)³ (or) (a/b) = (1/3).

Ratio of their surface area = 6a²/6b²= a²/b² = (a/b)² = 1/9 = 1:9.

Answer 2

Answer:

Step-by-step explanation:

Let their edges be a and b. Then,

a³/b³ = 1/27

(a/b)³ = (1/3)³

(a/b) = (1/3).

Ratio of their surface area

6a²/6b²

(a/b)² = (1/3)²

1/9=1:9

so, the ratio of their surface area is 1:9
