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.

Answer:
0.2kN
Step-by-step explanation:
An hydraulic jack works by the principle that pressure applied to one part in an enclosed liquid is transmitted equally in all parts of the liquid. this is in accordance with Pascal's principle.
Pressure= Force/Area
P=F/A
Pressure due to the load= Pressure due to input force for the system to be in balance.
Let force due to load be F₁, input force be F₂, Area at the load piston be A₁ and the area of the pipe through which the input force transmits be A₂, then,
F₁/A₁=F₂/A₂
10000N/5m²=F₂/1m²
F₂=(1000N×1m²)/5m²
F₂=200N
=0.2kN
