Answer:

Btw, this isn't my answer someone else answered this same question, but here's the credits to amanksingh010

Step-by-step explanation:

Ratio of their volumes => 343:729

Step-by-step explanation:

Let "a" be the side of 1st cube, and

"b" be the side of 2nd cube.

Given, ratio of surface areas of two cubes are 49:81

Hence, 6a^2/6b^2 = 49/81        [Surface area of a cube=6(side)^2]

6 will cancel out, i.e., => a^2/b^2 = 49/81

=> (a/b)^2 =  49/81

=> a/b = 7/9      [49 is square of 7 and 81 is square of 9]

So, we got the side of 1st cube 'a' = 7 and,

side of 2nd cube 'b' = 9

Ratio of their volumes =>

a^3/b^3 = 7/9           [Volume of a cube = (side)^3]

(a/b)^3 = 7/9 => (7/9)^3 => 343/729

Ratio => 343:729

To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon. (which is the same as the number of sides). There are 108° in each interior angle of a regular pentagon. This process can be generalized into a formula for finding each interior angle of a REGULAR polygon ...
