If two cubes have sides of length 5 cm and 6cm. The ratio of their respective surface areas is 36 : 25.
How to find the ratio of the surface area?
Using this formula to find the ratio
Ratio of their surface area = a /a'
Where:
a = 6
a' =5
Let plug in the formula
Ratio of their surface area = 6a² /6a'²
Ratio of their surface area = 6(6)² / 6(5)²
Ratio of their surface area = 36 / 25
Ratio of their surface area = 36 : 25
Therefore the ratio is 36 : 25.
