Question
If the perimeter of a square is 56 cm and the side of the square is double of the side of the cube, then find the volume of the cube.
Solution
We know that, perimeter of the square = 4 X side
So, 56 = 4 X side
So, the side of the square = 14 cm
So, the side of the cube = (14/2) = 7 cm
We know that, volume of the cube = side 3
So, the volume of the cube = 7 x 7 x 7 = 343 cm 3
