Question

if ratio of the sides of tow cubes are 2:3 the find the ratio of their surface area will be​

Answer 1

Answer:

4:9

Step-by-step explanation:

Ratio = 2:3

Let the sides be 2x and 3x

Area of cube 1 = 6×(2x)^2

Area of cube 2 = 6×(3x)^2

Ratio of their area=Area of cube 1/Area of cube 2

= 6×(2x)^2/6×(3x)^2

= 4/9

= 4:9
