Question

11. The ratio of the volumes of two cubes is 27 : 64. Find the ratio of their sides.
​

Answer 1

$\huge{\underline{\underline{\mathcal{\color{pink}{Answer:-}}}}}$

given. ratio of vol .= 27/64

. a cube / b cube = (3) cube/(4) cube

therefore sides of cube (a) and cube (b) are 3 and 4 respectively.

hence the ratio of their surface areas are 6 a square / 6 b square.

I.e = 9/16

Answer 2

Answer:

Answer is 3:4

Explanation:

We know the formula of volume of cube .. So.

length power 3 (l3) =27:64

when this will go under cube root u will get

3:4

hope this may help u to solve it with correct method....
