Answer 1

This is more math question than physics.

I would solve (a) by calculating area of a square:

since we know the ratio between meters and ken we can easily calculate area of the same square using both values:

for easiness sake lets take square with both sides equal to 1 ken.

then Area in square kens will be 1x1=1 square ken.

Since we know that 1 ken is 1.97 meters then our previous square also has sides equal to 1.97 meters.

Therefore Area of the same square will be 1.97x1.97 = 3.8809 square meters

Since we calculated area of the SAME square twice we can say that

1 square ken = 3.8809 square meters.

(B) is solved is same manner but using a cube

(C) Calculate the volume by using Cylinder volume formula

V=\[piR^{2}H \]

Where R is radius and H is height. You will obtain volume in cubic kens as a result. using answer from (B) it would be easy to convert the volume from cubic kens to cubic meters.
