Given


Required
Determine an expression for its volume
Find the volume
Volume of a cube is:

Where x represents the length of a side
So, volume of 2 cubes would be:


Solving (b): Volume when x = 4
Substitute 3 for x in 



<em>Hence, the volume is 128cm^3</em>
Answer:
9 cm
Step-by-step explanation:
Total surface area of a cube =486 cm²
We know that the surface area of the cube
=6l²
Therefore,
6l ²
=486
l² =81
l =9 cm
