Answer:
Step-by-step explanation:
volume=area *lenght
for area=2area of triangle +area of rectangle
a=2root(s(s-a)(s-b)(s-c))+7*4 {s is (a+b+c)/2 so s=(3+4+5)/2 finding 5 by pythagoras theorem so s=6}
a=2root(6(6-2)(6-4)(6-5))+28
a=2root48+28=41.85inch^2
now volume=41.86*5 given in fig height is 5
so v=209 inch^3
