a) Triangular Prism:
V= 4x3÷2xh
V=12/2
V=6cm2= A of B
V=6cm2x10cm=60cm3

b) Rectangular Prism:
V= lxwxh

V=8cmx6cmx10cm
V=480cm3

EXTRA QUESTION:
It is 1/3 Full
V=lxwxh
V=10cmx5cmx12cm
V=600cm3
600/3= 200cm3

Cylinder:
V= Pi x r2 x h
V= 3.14 x 5 x 5 x 10
V= 785cm3

AREA OF A CIRCLE:
Pi x r2
A=3.14 x 52
A=3.14 x 25

A= 78.5cm2
