volume of pyramid  =  (1/3)(area of base)(altitude)

 

area of base  =  area of rhombus  =  (1/2)(10)(24)  =  120   square units

 

altitude  =  18

 

volume of pyramid  =  (1/3)(120)(18)

volume of pyramid  =  (1/3)(2160)

volume of pyramid  =  720   cubic units

 

You almost had it...maybe just a typo?  smiley
