The total surface area of a cube is 384 cm2. Calculate the side of the cube.

Given the Total surface area of a cube = 384 cm2

As we know, the Total surface area of a cube = 6 (side of the cube)2 = 6a2



So, according to the question:


Total Surface Area of a Cube = 384 = 6a2





= ±8


a = 8cm (side can’t be negative)
