Ben needs to replace two sides of his fence. One side is 367 9/100 meters long, and the other is 329 3/10 meters long. How much
Flura [38]

Answer:

696\frac{39}{100} meters fence

Step-by-step explanation:

Ben needs to replace two sides of his fence.

The length of one side of fence =  367\frac{9}{100} meters

The length of other side of fence = 329\frac{3}{10} meters

to calculate the length of fence that Ben need to buy we will add the length of both sides.

367\frac{9}{100} + 329\frac{3}{10}

= \frac{36709}{100} + \frac{3293}{10}

= \frac{36709+32930}{100}

= \frac{69639}{100}

= 696\frac{39}{100} meters

Ben need to buy  696\frac{39}{100} meters fence.

If lateral surface area of cube is double then the ratio of volume of new cube to original cube ​
Solnce55 [7]

Answer:

  2√2

Step-by-step explanation:

The area ratio is the square of the side length ratio, so the ratio of side lengths is √2.

The volume ratio is the cube of the side length ratio, so the new cube has a volume that is (√2)³ times that of the original.

The volume ratio is 2√2.
