**Rectangular Prism :**

**Rectangular Prism net:**

*Formula :*L x W = a

# x # = a

#cm = a

L x W = a

# x # = a

#cm(2) = a

TSA

= S1 + S2 + S3

= # + # + #

=tsa .

**Solution :**

**Triangle Prism :**

area of triangles :

= b x h / 2

= # / 2

= # cm(2)

= b x h / 2

= # / 2

= # cm(2)

TSA

=S1 + S2 + S3

=# + # + #

=#cm

=S1 + S2 + S3

=# + # + #

=#cm

**Cylinder:**

**Cylinder net:**

**Formula:**First find the cicumference of the circle to get the length of the rectangle.

πd = c

3.14 x # = c

# = c

Then find the area of the circle.

If you're given the diameter. You have to find the radius first.

d/2 = r

#/2= r

# = r

#/2= r

# = r

area of circle:

π x r x r = area of circle

3.14 x # = area of circle

π x r x r = area of circle

3.14 x # = area of circle

# cm (2) = area of circle

Then find the Lateral Area of the square.

L x W= L.A

# of circle circumference x #= L.A

# cm= L.A

TSA

= circle + circle + L.A

= # + # + #

= # cm(2)

# cm= L.A

TSA

= circle + circle + L.A

= # + # + #

= # cm(2)
