What is the volume of the a cube with a side of length 11 unitsA. 33 units
B. 121 units
C. 1331 units
D. 14641 units

Answers

The volume of a cube is

(length of a side) x (length of a side) x (length of a side)

usually written as (length of a side)³ or (length of a side) cubed.

If the length of a side is 11 units, then the volume is

(11 units) x (11 units) x (11 units) = 1,331 units-cubed.

None of the choices on the list is correct. The nearest one is 'C'.
It has the correct number but the wrong units.

Volume of a cube is
Volume=length×width×height

Substitute in the value
Volume=11×11×11

Volume=1331

The answer to your question is C. The volume of a cube with a side length 11 is 1331.

I hope this has helped.

There are 5 "parts" and 3 "parts"; which total "8 parts" (5 + 3 = 8); so, each part must be 56/8 = 7. so each part must be 56/7 = 8
5 x 7 is 35
3 x 7 is 21

So the answer is 35:21 .

About 7/10 of the human body is water. If a person weighs 130 pounds about how many pounds are water?

Answers

Amount of water=(7/10) * Weiht of the person
Amount of water=0.7 * 130 pounds=91 pounds.

answer: 91 pounds of water.

Final answer:

Given that the human body is about 70% water, a person who weighs 130 pounds would carry about 91 pounds of water weight.

Explanation:

The question is asking us to calculate the amount of water by weight in a human body. We can solve this by using a percentage (or a decimal equivalent) and multiplying that by the person's total weight. Given that 7/10 (or 70%) of the human body is water and the person weighs 130 pounds, we simply multiply 130 by 0.7 (the decimal equivalent of 7/10).

To calculate: 130 pounds * 0.7 = 91 pounds. Therefore, about 91 pounds of a person who weighs 130 pounds is water.
