Question

A cube of edge 5 cm is cut into cubes each of 1 cm the ratio of the total surface area of one of small cubes to that of large cube

Answer 1

area of bigger cube is 5×5=25
area of small cube is 1×1=1
therefore ratio is 1:25

Answer 2

Answer: Required ratio is 1:25.

Step-by-step explanation:

Since we have given that

Length of large cube = 5 cm

Length of small cube = 1 cm

Surface area of cube is $6a^2$

So, Ratio of total surface area of small cube to total surface area of large cube

is given by

$6(1)^2:6(5)^2\\\\=1:25$

Hence, Required ratio is 1:25.
