A rectangular block of metal is 0.24 m long, 0.19 m wide and 0.15 m high. If the metal block is melted to form a cube, find the
DanielleElmas [232]
<h3>Answer: approximately 0.19 meters long</h3>

The more accurate value is 0.18982439916059 but this value isn't exact

========================================================

Explanation:

The volume of this rectangular block is 0.24*0.19*0.15 = 0.00684 cubic meters.

If we had a cube of this volume, then it has some side length x such that x^3 = 0.00684

Apply the cube root to both sides. This is the same as raising both sides to the 1/3 power

x^3 = 0.00684\\\\x = \sqrt[3]{0.00684}\\\\x = (0.00684)^{1/3}\\\\x \approx 0.18982439916059\\\\x \approx 0.19\\\\

The side length of the cube is approximately 0.19 meters long

Least to greatest;]
alexandr1967 [171]

Answer:

Least to greatest is: 0.0625, 6.75% and \frac{7}{10}.

Step-by-step explanation:

Given:

The three quantities to compare are:

6.75%, 0.0625, and \frac{7}{10}

Let us convert each into percentage.

6.75% is already in percentage.

We multiply a number by 100 to convert it to percentage form.

So, 0.0625\times 100=6.25\%

\frac{7}{10}\times 100=\frac{700}{10}=70\%

Now, on comparing all the three percentage, we conclude that,

70% is the greatest and 6.25% is the least.

So, order from least to greatest is:

6.25\%
