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= 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

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

r= d/2

r= 12/2

r=6cm

v= π x r x h
