To work out
volume you have
to work out the
area of the front side of
the shape and
times it by how
long it is.
To work out how do do the
shape below you will need to
times the 2 and the 5 to work
out the front face of the shape.
Once you have done that you
will need to times that by the
length of the shape, when you
have done that all you have to
do is times your first answer
with the length so it would be
10x8=80 and that's your answer.
