Area of the 6 boxes gives 150cm2
This means that area of 1 box is 150 divided by 6 = 25cm2
One side of the square is therefore the square root of 25 = 5cm
The net shown in the picture will give you a cube when folded. The cube will have the same length of sides (height = length = breadth = 5cm).
Volume of a cube = height x length x breadth = 5 x 5 x 5 = 125cm2
