Lateral surface area is different then regular surface area. It is the area of the faces that are not the bases. In this case there is 4 square faces that are not the bases. So...

Answer:

The length of one edge of the cube is 6 centimeters.

Step-by-step explanation:

The lateral surface area of a cube is

A=4a^2

where a is the length of one edge of a cube.

It is given that the lateral surface area of the square is 144 square centimeters.

Substitute A=144 in the above formula.

144=4a^2

Divide both sides by 4.

36=a^2

Taking square root both the sides.

\sqrt{36}=\sqrt{a^2}

6=a

Therefore the length of one edge of the cube is 6 centimeters.

Answer:

Scalene

Step-by-step explanation:

With this question, it's best to draw it out or we can use process of elimination.

We can rule out Right as the triangle is already obtuse (it can't be both).

We can rule out Equilateral as all the sides are not equal.

We can also rule out Isosceles as this triangle requires 2 sides to be equal, which clearly, they aren't.

Therefore, we are left with Scalene (C) which is your answer.

A scalene triangle has no identical sides or angles, and can be obtuse, right or acute.

Hope this helps,
