Question

The volume of two cibes are in ratios 8:1 then find the ratios of these adges

Answer 1

Correct Question: The volume of two cubes are in the ratio 8:9. Then find the ratio of their edges.

GIVEN:

The volume of two cubes = 8:1

We know that,

The volume of cube = a³

V1: V2 = 8:1

(a1)³/(a2)³ = 8/1

a1/a2 = ³√(8/1)

a1/a2 = 2/1

a1:a2 = 2:1

Therefore, the ratio of their edges is 2:1.

Answer 2

ANSWER :-

The volume of two cubes = 8:1

$\huge\boxed{VOLUME \:\: OF \:\: CUBE =³}$

Volume of first cube : Volume of second

cube= 8:1

(a1)³/(a2)³ = 8:1

(a1)³/(a2)³=8/1

a1/a2 = ³√8/1

a1/a2 = 2/1

a1:a2 = 2:1

Therefore, ratio of their edges is 2:1
