August 27, 2021 | education

| First, let’s draw a cube, in which we designate an edge at 2.5 cm.

Since in a cube all the edges are equal, the length, width and height are equal to 2.5 cm.

Whereas, to find the surface area of a cube, you need to multiply the perimeter of the base by the height.

Then we find the perimeter of the base: 2.5 * 4 = 10 cm.

Therefore, the total surface area is: 10 * 2.5 = 25 cm2.
