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

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