Pls this is super urgent
an artist has
20 triangular prisms
like the one shown. he
decides to use them to
build a giant triangular 1.4 m
prism with a triangular base of
length 5.6 m and height 6.8 m.
a) does he have enough small prisms?
b) what is the volume of the new prism
to the nearest hundredth of a metre?
