Question

The sum of the lengths of the edges of a cube is equal to four times the perimeter of a square. If a quarter of a numerical value of the valume of the cube is equal to numerical value of the area of the square then the length of one side of square is ?

Answer 1

let cube since be s1 and started side be s2

12s1 = 16s2

3s1 = 4s2

s1³/4 = s2²

4s2³/3/4 = s2²

s2³ = 3s2²

s2 = 3

therefore side of square is 3cm
