This video will also help you find the volume of a cube.

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

* PICTURES ON THE TOP IN ORDER.
