3 0

It would be 340%. First, you need to find out what the fraction is for 2/5. 2/5 as a decimal would be .4. Next you put that back with the three which is 3.4. After that, you need to turn that into a percentage by multiplying it by 100 which then equals 340. add the % to it and that gives you 340%.

A rectangular solid and a cube are of equal volume. If the rectangular solid is 20 centimeters long, 5 centimeters wide, and 10

Answer:

10 centimeters.

Step-by-step explanation:

First, we need to remember what's the formula to get the volume of a rectangular solid and a cube.

The volume of the first equals:

Volume = Length x Width x Height

While the volume of the cube is:

$Volume = a^{3}$ where a is the edge.

We are given the measures of the rectangular solid so we can calculate its volume:

$Volume= (20)(5)(10)=1000$ cubic cms.

Now, we know that both the volume of the rectangular solid and the cube are the same so we will use this information to calculate the edge of the cube.

$1000=a^3 \\\sqrt[3]{1000} =\sqrt[3]{a^3} \\10=a$
