So each dimention is 32 by 8 by 10
so the surface area=2 times(8 times 10)+(2 times (32 times 10))+(2 times (8 times 32))=2 times 80+2 times 320+2 times 256=1312
if halved
just divide each by 2
(2 times 4 times 5)+(2 times 16 times 5)+(2 times 4 times 16)=(2 times 20)+(2 times 80)+(2 times 64)=40+160+128=328
the new surface area is 328 mm^2
1)b
2)a
Let me know if u want me to show my work
Answer:64
Step-by-step explanation:
67
37 more than t would simply be defined as 
That's all!
Its c first find area of the whole thing with piece cut out.(240) then of the cut out piece (12) 240-12=228 C
