Question

If the ratio of volumes of two cubes is 1 : 64, then find the ratio of their surface area. ​

Answer 1

given volume of two cubes =1:64

W.K.T volume of two cubes =a^3

then a1^3:a2^3=1:64

therefore a1=1

a2=4

surface area of cube =6a^2

surface area of a1 cube =6×1

surface area of a2 cube =6×16

then ratios of their surface area =6×1:6×16

=1:16
