First you need to work out how much string is needed -
256 pieces needed x 40cm each:
256 x 40 = 10240cm
Then, convert to metres (100cm = 1m)
10240 / 100 = 102.4m
Then, you work out how many balls are needed:
30 can fit into 102.4 3 times with .41m to spare. So, you need three balls of string, PLUS another one to cover the 41cm
So to conclude: 4 balls of string are needed.
The solution to this question is 39.0625.
This is because you will need to multiply the width by height. As this is in square feet it will be irrespective of which two sides we choose.
The calculation that will need to be done is the following :
6.25ft X 6.25ft which will equal 39.0625.
6.25 has three significant digits so rounding 39.0625 off to three significant digits is 39.1 square feet
Cross-multiply so that 8(3x + 1) = 14(2x)
Distribute the 8 and 14 into the parentheses:
24x + 8 = 28x
Subtract 24x from both sides:
8 = 4x
Divide both sides by 4:
x = 2
