Volume Post

Triangular Prism

b x h1 ÷ 2 x h2
3 x 8.5 divided by 2 x 5
127.5 divided by 2
=63.75 m

Square Prism
Aoh x h
L x W x H
20 x 8 x 16
=2560 cubic centimetres


Triangular Prism


L x W x H
4 x 8 x 6.5
208 divided by 2 = 104
104 divided by 8 = 13 cubic centimeters
3 x 13 = 39 cubic centimetres


Circular Prism


V= pie r squared
3.14 x 6 x 6 = 113.04
113.04 x 15 = 1695.6 cubic centimetres
