{n}^{3}  + 512 \\  =  {(n)}^{3}  +  {(8)}^{3}  \\ by \: using \:  {a}^{3}  +  {b}^{3}  =  (a + b)(  {a}^{2}  - ab +  {b}^{2}) we \:  \:  \: get \\  = (n + 8)( {(n)}^{2}   - n \times 8 +  {(8)}^{2} ) \\  = (n + 8)( {n}^{2}  - 8n + 64)

Hope you could get an idea from here.

A candy store called "Sugar" built a giant hollow sugar cube out of wood to hang above the entrance to their store. It took 13.5
Sunny_sXe [5.5K]

Answer:

\frac{27}{8}m^3 or 3.375m^3

Step-by-step explanation:

The formula for volume is Base * Height * Width; and the formula for area is Base * Height.

This problem mentions the structure is a cube and therefore it is assumed that every wall has the same area. Since there are 6 sides to a cube you divide the total amount of ft which make up this cube to know the area to each wall.

13.5 m/6 = 2.25 or \frac{9}{4} m per wall

With the area of each wall you can find the base and height:

base * height =  area

b=\sqrt{\frac{9}{4} } = \frac{3}{2}

base = \frac{3}{2}m

height = \frac{3}{2}m

since: base=height=width, the width also equals \frac{3}{2}m

volume = (\frac{3}{2})^3= \frac{27}{8}

sorry it took so long for you to get an answer
