Answer:
V=4960in^3
S.A=2116in^2
Explanation:
36x2
1- 72in^2
5-2=3in
8x3
2- =24in^2
5-2=3in
5+3=8in
8x10
3- =80in^2
36-(10+8)=
0.5×18×8
4-=72in^2
72+24+80+721
C.S.A=248in^2
V= 248×20
=4960in^3
248x2
1- =496in^2
36x20
2- =720in^2
20×2
3- =40in^2
20×5
4- =100in^2
20×8
5- =160in^2
20×20
6- =400in^2
20×10
7- =200in^2
=496+720+40+100+160+400+200
=2116in^2
