TRAINGLE 1: AREA OF BASE X HEIGHT
15 X 3/2=22.5M2
22.5 X 8 = 180M3

SQUARE: AREA OF BASE X HEIGHT
20 X 8 = 160CM
2
160 X 8.5 = 1360CM
3

TRAINGLE 2: AREA OF BASE X HEIGHT 3/8=0.375
4 X 8 =32 32/2= 16
16 X 6.5 = 104M3
104X0.375=39


CYLINDER: AREA OF BASE X HEIGHT
3.14 X 6 X 6 = 113.04CM2


113.04 X15=1695.6CM3

Dorian"s 8-14 Total Surface Area And Volume Post

V= BxH ÷ 2 x height
V=3x5÷ 2= 7.5m3

V=7.5x8.5 = 63.5m3




















V= bxh divide 2 x hV=LxWxH
V=20cm x 8cm = 160cm
V= 160 x 16=2.560
V= 2,560 cm3









V= BxH ÷ 2 x height
v= 4x8 ÷, 2 x h
v= 32 ÷ 2 x h
v= 16 x 6.5
v=104cm2
In able to find 3/8 : 104 ÷ 8 x 3 which is
V= 39cm3















=Area of the base x the Height
R= ÷ 2

R= 12÷2

R=6cm

V= π x r x height

V= 3.14 x 62 x 15

V= 3.14 x 36 x 15

V= 1695cm3

V= bxh divide 2 x height
=3x5 divide 2= 7.5m2
=7.5x8.5 = 63.5m2








V= lxwxh

=
2560cm2= 20x8x16












V= bxh divide 2 x h
= 4x8 divide 2 x h
= 32 divide 2 x h
= 16 x 6.5
=104cm2
To find 3/8 u can do 104 divide by 8 x 3 which is
39cm2







V= Pi, Radius squared x h
= 3.14x6x6x15
=1695.6cm2

Ghelo's Surface Area Post and Volume




Triangular Prism : Base x Height divided by 2 x Height
3 x 5/2 =
15/2=
7.5m2
7.5 x 8.5 = 63.75m3
Rectangular Prism: Length x Width x Height
20 x 8 = 160cm2
160 x 16 = 2560cm3

Triangular Prism : Base x Height divided by 2 x Height
4x8/2=
32/2=
16cm2

16 x 6.5 = 104cm3
To find 3/8 you can do two ways
1.3/8 = 0.375 0.375 x 104 = 39cm3
2. 104/ 8 = 13 cm 13 x 3= 39cm3



Cylinder: Area of Base x Height
