Question

2 A chocolate bar is made in the shape of a
triangular prism. The triangular face of the prism
is equilateral and has an edge length of 4 cm and a
perpendicular height of 3.5 cm. The manufacturer
also sells these in special packs of six bars
arranged as a hexagonal prism. If
the prisms are 20 cm long, calculate:
a the cross-sectional area of the
pack,
b the volume of the pack.
3.5 cm

Answer 2

Answer:

2a=42cm^2  2b=840cm^2

Step-by-step explanation:

2)a.   There are 6 chocolate bars

 so, cross-sectional area of the pack= 0.5bh * 6

                                                             = 0.5*4*3.5*6

                                                              = 42cm^2

2)b. The volume of the pack= cross-section area*Length

                                              = 42*20

                                              =840cm^3
