5. Find the lateral surface area of the net of
the cube.
1.8 cm

Given:

Given that the side length of the cube is 1.8 cm

We need to determine the lateral surface area of the cube.

Lateral surface area of the cube:

The lateral surface area of the cube can be determined using the formula,

where a is the side length.

Substituting a = 1.8 in the above formula, we get;

Squaring the term, we get;

Multiplying, we get;

Thus, the lateral surface area of the cube is 12.96 cm²
