A cube with side length m has a volume of 343 cubic centimeters. The following equation shows the volume of the cube.m^3 = 343m

What is the side length of the cube in centimeters?

Answers

The side length of the cube in centimeters is equal to 7.

Given the following data:

Volume of cube = 343 cubic centimeters.

To calculate the side length of the cube in centimeters:

How to calculate the volume of a cube.

Mathematically, the volume of a cube is given by the following formula:

$Volume = m^3$

Where:

m is the length of sides of the cube.

Substituting the given parameters into the formula, we have;

$343 = m^3\n\n$

Taking the cubic root of both sides, we have:

$m=\sqrt[3]{343}$

m = 7 centimeters.

Answer:

7 cm

Step-by-step explanation:

Given : A cube with side length m has a volume of 343 cubic centimeters.

To Find: What is the side length of the cube in centimeters?

Solution:

Volume of cube = $Side^3$

The side of the cube is m

So, Volume of cube of m = $m^3$

Since the volume of cube is 343 cubic centimeters

So, $m^3=343$

$m=\sqrt[3]{343}$

$m=7$

Hence the length of the cube is 7 cm.

What is 1/9 of 63% of $6,000?

Answers

Answer:

The answer is $420

Step-by-step explanation:

The procedure is multiply the number 6000 by 63% and $(1)/(9)$ . The order of these multiplying doesn't matter.

The percentage number can be changed into a fraction number following the next rule:

Give a x number in a range from 0 to 100:

x%= $(x)/(100)$

So,

63%= $(63)/(100)=0.63$

$(1)/(9)*0.63*6000=420$

Finally, the answer is $420

The answer is $420. Multiply 6,000 by 0.63 to find 63% of 6,000. That gives you 3780. Then to find 1/9 of 3780, divide it by 9. The answer is 40.
