Answer with Step-by-step explanation:
We are given that
We have to explain that why the function is discontinuous at x=2
We know that if function is continuous at x=a then LHL=RHL=f(a).
LHL=Left hand limit when x <2
Substitute x=2-h
where h is small positive value >0
Right hand limit =RHL when x> 2
Substitute
x=2+h
LHL=RHL=
f(2)=1
Hence, function is discontinuous at x=2
You can write it in two types of fractions:
1) ur answer will be 26 and 2/10 which can be simplified to 26 and 1/5
2) ur answer will be 262/10 which can be simplified to 131/5
The first is the more recommended way of writing your answers.

Answer:
32cm^2
Step-by-step explanation:
The surface area is the sum of surfaces of all walls.
The 3 visible walls are 2cm*3cm, 2cm*3cm and 2cm*2cm.
The 3 invisible walls are each identical to the parallell walls.
The surface area is
2 * (2cm*3cm + 2cm*3cm + 2cm*2cm) = 2 * (6cm^2 + 6cm^2 + 4cm^2) = 2 * 16cm^2 = 32cm^2
