I think the answer is x= 11 but im not sure <span />
The percentage of Change in time is an decrease
Find the volume of the candle using the formula for volume of a cylinder:
V = PI x r^2 x h = 3.14 x 3.4^2 x 6 = 217.79 cubic cm. Round to 217.8
Find the volume of the block: V = l x w x h = 15 x 12 x 18 = 3,240 cubic cm.
Now divide the volume of the block by the volume of a candle:
3240 / 217.8 = 14.88
Round to the nearest tenth = 14.9 candles.
53 3/4=53.75
To find out how many 4ft ropes you can make divide 53.75 by 4
53.75/4=13.4375
You can make 13 4ft ropes out of a 53.75ft rope
