We can split the prism into two parts

 

The "top" part  has a volume of :

 

5cm x 6cm x 4cm     =   120m^3

 

The "bottom" part  has a volume of :

 

15cm x 6cm x 8cm  =  720 cm

 

So.....the total volume =  120cm^3 + 720m^3  =  840cm^3

 

 

 

cool cool cool

12*5=60

10*8=80

60+80=140

140*6=840

 

Thanks to those who helped.
