Question

if the ratio of the volume of two is 1:8 the find the ratio of the total surface area of the two cubes​

Answer 1

Answer:

Step-by-step explanation:

Volume=1:8

Then side=1:2

Then surface Area=6:24=1:4

ANS-1:4

Answer 2

Given :-

Ratio of volume = 1:8

To Find :-

Ratio of TSA

Solution :-

We know that

Volume of cube = a³

Let the side be a and a'

a³/a'³ = 1/8

a/a' = ∛1/∛8

a/a' = 1/2

Now

Surface area of cube = 6a²

SA/SA' = 6(1)²/6(2)²

SA/SA' = 6 × 1/6 × 4

SA/SA' = 6/24

SA/SA' = 1/4
