- Find F2–4 for the surfaces shown in Fig
Homework Answers
Each surfaces (marked as 1,2,3,4) are rectangular.
So, Area of first surface (marked as 1)
Here, length is 0.4m and height is 0.6m.
So, area is 0.4*0.6=0.24 square meter.
Area of second surface is 0.4*0.6=0.24 square meter
Area of third surface is 0.4*0.6=0.24 square meter
Area of 4th surface (marked as 4)
(1/2)*1.2=0.6 square meter
Note: here question is confusing. F2 is not declared in the question. if F2 being the area of 2nd surface, which is marked as 2, then F2=0.24 square meter
Similarly, F3=0.24 square meter
and, F4=0.6 square meter
