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
v= 3.14 x 62 x 15
v= 3.14 x 36 x 15
v= 1695.6cm3
