Question

a cube of Edge 5 cm is cut into cubes each of 1 cm the ratio of the total surface area of one small cube to that of the last us

Answer 1

TSA of bigger cube
= 6 × 5 ^2 = 150 cm^2

TSA of smaller cube
= 6 × 1^ 3 = 6 cm^2

Therefore,

Ratio of Tsa of smaller cube to bigger cube =

=> 6 : 150

=> 1 : 25 ................. $ANS$

Answer 2

edge of bigger cube = 5cm
edge of each small cube = 1cm
tha of a cube = 6(a) sq

tsa of bigger cube =6(25) = 150 cmsq
tsa of each small cube =6(1) = 6 cmsq

taking out the ratio of both we get 6:150 that is 1/25
ans= the ratio of both the cubes =1:25
