Question

Answer for 20pointS alll

Answer 1

1) a=2(wl+hl+hw)
w=24
l=18
h=15
a=2(24*18+15*18+15*24)
a=2124----> D

2) so we find the rectangular sides first:
    6.4*7*2=89.6   (there are two rectangular sides so we multiplied by 2)
   Then triangular sides (front and back)
    1/2*5*8 *2= 40
   Lastly, the bottom made of the same material:
    8*7= 56
    Add it all together  89.6+40+56=185.6 ft^2
    A
3) C
4) F
