* If you can't read the picture (;
5 x 3.2 = 16
5 x 3.2 = 16
5 x 11.5 = 57.5
5 x 11.5 = 57.5
11.5 x 3.2 = 36.8
11.5 x 3.2 = 36.8
16 + 16+ 57.5 + 57.5 + 36.8 + 36.8 =220.6 cm2
TSA = 22o.6 cm2



Cylinder Volume and Volume Problems






v= b x h^1 /2 x h^2
v= 12 x 15 / 2 x 15
v = 1,350cm^3

My assumptions is that the volume of the cheese from the block is 1,350 cm^3




Outside
d/2 = o.5m^2
v=π.r.r.h
v=3.14.o.5.o.5.10
v=o.785m^2.10
v=7.85m^3

Inside
d/2=0.4m^2
v=π.r.r.h
v=3.14.0.4^2.10
v=5.024m^3

7.85m^3 - 5.85m^3 = 2.86^3 or 2.9m^3

The volume of the culvert is 2.9m^3
