The volume of a cube is 64 cubic inches. Which expression represents s, the length of a side of the cube?
vlabodo [156]

Answer:

<h2>Therefore the length of a side of a cube is \sqrt[3]{64}\ or\ 4</h2>

Step-by-step explanation:

The volume of a cube is expressed as L³ where L is the length of each side of the cube.

Given volume of a cube = 64in³

On substituting;

64 = L³

Taking the cube root of both sides to determine L we have;

\sqrt[3]{64} = (\sqrt[3]{L})^{3}\\\sqrt[3]{64} = L\\L=4

Therefore the length of a side of a cube is \sqrt[3]{64}\ or\ 4

katrin [286]

Answer:

The number of sides the polygon have 9

Step-by-step explanation:

Given in question as :

For The circle ,  the central angles measure be 40 °

Let the number of sides of polygon =  n

Now . as we know

External angle =  \frac{360^{\circ} }{n}

Or ,           40° = \frac{360^{\circ} }{n}

Or, \frac{360^{\circ} }{n} = 40°

Or, \frac{360^{\circ} }{n} = 40°

So, n = \frac{360^{\circ} }{40^{\circ}} = 9

Hence The number of sides the polygon have 9      Answer
