B.


The volume of B is greater than the volume of A.



C.


The surface area of B is greater than the surface area of A.


D.


The volume of A is greater than the volume of B.


Last one seems tricky

Answer 1

the area of the first prism is:
A_1=2*(2*6+2*5+6*5)=...

Answer 2

namely prism A

Answer 3

i got 760

Answer 4

are you sure?

Answer 5

yeppers

Answer 6

ill double check

Answer 7

more steps:
A_1=2*(12+10+30)=...

Answer 8

104

Answer 9

ok!

Answer 10

:D

Answer 11

whereas the area of prism B is:
A_2=2*(5*3+5*4+3*4)=...

Answer 12

664

Answer 13

more steps:
A_2=2*(15+20+12)=...

Answer 14

94

Answer 15

correct!

Answer 16

now the volue of prism A is:
V_1=2*6*5=...

Answer 17

60

Answer 18

ok!

Answer 19

finally the volume of the prism B is_
V_2= 5*3*4=...

Answer 20

60

Answer 21

ok! so both prisms have the same volume

Answer 22

oh yeah, they do :3

Answer 23

so, what is the right option?

Answer 24

so B?

Answer 25

no not b

Answer 26

no, since both prisms have the same volume

Answer 27

it doesnt give me an option to say they r the same ;-;

Answer 28

Hint:
area of prism A is 104
whereas area of prism b is 94

Answer 29

A

Answer 30

wait but i thought they were both 60?

Answer 31

and 104 is greater than 94
that's right!

Answer 32

each volume is 60

Answer 33

:D yay!

Answer 34

:)

Answer 35

Thank you!

Answer 36

thanks!! :)

Answer 37

np :D Thank you for helping me!
