the total volume of a cube is 360 inches to the third power how do you write 2 different possible sets of diminsions for the cube

Answers

If it's really a cube, then it can have only one set of dimensions.
Actually, only one dimension ... the length of every edge is the
same number.

The volume of a cube is the cube of its edge length. So the
length of every edge is the cube root of its volume.

But the dimension can sometimes be written in different ways.

Volume = 360 inch³

Edge length = ∛(360 inch³)

      = ∛360 inches

      = 3 ∛(13 and 1/3) inches

      = 4 ∛5.625 inches

      = 5 ∛2.88    inches

    = 6 ∛(1 and 2/3) inches .

Well,

Since it's a cube, there will only be one real dimension, and that will be the cube root of 360.

$\sqrt[3]{360} = 2\sqrt[3]{45}\ inches$

The only way to write different dimensions is to write using different units.

12 in. = 1 ft.

$\frac{2\sqrt[3]{45}}{12} = \frac{\sqrt[3]{45}}{6}\ feet$

Try to simplify 72/6+85/6

Answers

72 + 85 = 157

157/6 = 26
26*6 = 156
26 and 1/6

Answer: 26 and 1/6

72/6+ 85/6
= (72+ 85)/6
= 157/6
= (156+1)/ 6
= 156/6+ 1/6
= 26+ 1/6
= 26 1/6

The final answer is 26 1/6~
