A) 1 : 125
B) 1: 5
C) 1: 625
D) 1: 25
Correct Answer: D
Solution :
Surface area of a small cube \[=6\times {{(edge)}^{2}}=6\times 1=6\,c{{m}^{2}}\] Surface area of the large cube \[=6\times {{(5)}^{2}}=6\times 25\,\,c{{m}^{2}}\] \[\therefore \] Required ratio \[=\frac{6}{6\times 25}=\frac{1}{25}\] i.e., 1: 25You need to login to perform this action.
