10%
= 10/100
= 1/10
10% in its simplest form is 1/10~
Volume of a triangular prism is given by V = Al where A is the area of the triangular cross section, i.e.

, and l is the length of the triangular prism.
Here, b = 8cm, h = 9cm, and l = 5cm.

Therefore,
Answer:
I don't remember the name of the law, but it states that when resistors are connected in series they put up one singular resistance. so,
Let smaller resistance be x
greater resistance is 3x
According to the question,
x+3x=12
4x=12
x=3
therefore,
resistors are of 3 ohms and 3×3=9 ohms
