Thimpu arranges cubes of volume 1 cu. cm into a 7 x 7 layer as shown below. How many such layers should be stacked one above other to form a cube of volume 343 cu. cm ?

Open in App

Solution

Number of cubes in one layer shown = 7 x 7
= 49.
Volume of each small cube = 1 cu. cm
So, Volume of the shown layer = 49 cu. cm
Volume of cube to be formed = 343 cu. cm

So, Number of such layers to form cube = 343 ÷ 49 = 7

7 such layers are to stacked one above other to form a cube of 343 cu. cm
