Question

the ratio between the lengths of the edges of two cubes are in the ratio 3:2. find the ratio between their total surface area

Answer 1

Answer:

9 : 4

Step-by-step explanation:

given ratio of lengths of sides = a : b , then

ratio of surface area = a² : b²

here ratio of sides = 3 : 2 , then

ratio of surface areas = 3² : 2² = 9 : 4
