Question
Anan made a big cube having double the side of your paper cube. How many of your paper cubes will fit in it? Try doing it by collecting all the cubes made in your class.
Solution
Length of the side of paper cube = 7 cm
Length of the side of Anan’s cube
= 2 × 7 cm
= 14 cm
We can fit 4 paper cubes, each of side 7 cm in the first layer of the big cube.
As the length of each side of the big cube is 14 cm, there will be a total of 2 layers with each layer containing 4 paper cubes.
So, number of paper cubes in 2 layers = 2 × 4 = 8
Thus, 8 paper cubes will fit inside Anan’s big cube.
