Question

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

Answer 1

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,

`LSA=4a^2`

where a is the side length.

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

`LSA=4(1.8)^2`

Squaring the term, we get;

`LSA=4(3.24)`

Multiplying, we get;

`LSA=12.96`

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