The volume of a cube is 27 n Superscript 27cubic units. What is the length of one side of the cube? 3 n cubed units 3 n Superscr

NeTakaya

The length of side of cube is $3n^9$ units

Solution:

Given that, volume of cube is $27n^{27}$ cubic units

To find: length of one side of cube

The volume of a cube is given as:

$v = a^3$

Where, "a" is the length of side of cube

Substituting the given value of volume we get,

$27n^{27} = a^3$ ------ eqn 1

We know that,

$27 = 3 \times 3 \times 3 = 3^3$

Substitute the above in eqn 1

$3^3 n^{27} = a^3$

Now again substitute for 27 = 3 x 9

$3^3n^{3.9} = a^3$

Take 3 as common power

$(3n^9)^3 = a^3$

By taking cube roots on both side,

$3n^9 = a\\\\a = 3n^9$

Thus length of side of cube is $3n^9$ units

Which statement is true? Millimeters are larger than centimeters. Millimeters are larger than centimeters. Meters are larger tha

jasenka [17]

Given :

Conditions :

1) Millimetres are larger than centimetres.

2) Meters are larger than kilometres.

3) Millilitres are larger than kilolitres.

4) Kilograms are larger than grams.

To Find :

Which conditions are correct.

Solution :

1) Millimetre is 0.001 m and cm is 0.01 m .

So, option 1 is correct.

2) Kilometer is 1000 m .

So, option 2 is also correct.

3) Millilitres is 0.001 L and kilolitres is 1000 L .

Therefore, this is not correct.

4) Kilogram is 1000 g .

Therefore, this is also correct.

Therefore, option 1 , 2 and 4 are correct.

Hence, this the required solution.
