Answer:
4. 16 times longer
5. 4 times longer
6. 64 times longer
Step-by-step explanation:
Solving (4):
Let the length and with of the object be x and y

Apply Scale Factor of 4






Divide Area₂ by Area₁


<em>Hence;</em>
<em>The surface area will increase 16 times longer</em>
Solving (5):
Let the length and with of the object be x and y

When the object is increased by a scale factor of 4;
It means that the Area is increased by a scale factor of 4
i.e.


Divide Area₂ by Area₁



<em></em>
<em>Hence;</em>
<em>The surface area will increase 4 times longer</em>
<em></em>
Solving (6):
Let the length, width and height of the object be x, y and z


Apply Scale Factor of 4








Divide Volume₂ by Volume₁


<em>Hence;</em>
<em>The volume will increase by 64 times</em>
