<u>Given</u>:
Given that the side length of the cube is 1.8 cm
We need to determine the lateral surface area of the cube.
<u>Lateral surface area of the cube:</u>
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
Answer:
Step-by-step explanation:
<em>Note all arguments of trigonometric functions are in degrees.</em>
<em />
Since tan(35)=4/(longer dotted leg of the triangle), the length of this longer dotted leg is thus 4/tan(35).
Since A=bh, the area is (4/tan35)(12), and you can just plug this into a calculator.
