Answer:

Step-by-step explanation:
We want to find the lateral surface area of the cube.
The lateral surface area of a cube is given as:

where a = length of side of the cube
Therefore, given that the length of the side of the cube is 2.5 inches, the area you need to paint is:

I think the answer is 20 but I'm not sure
B^3z + 27z
=z(b^3 + 3^3)
=z(b+3)(b^2 -3b + 9)
because
<span>a^3 + b^3 = (a+b)(a^2 − ab + b^2)
</span>
answer
z(b+3)(b^2 -3b + 9)
Uh english please and i could help maybe??
