Answer 2

you want to think about the volumes of each and compare them

Answer 3

rectangular prism is just WLH
Pyramid though will differ

Answer 4

i think D

Answer 5

well IDK we need to justify that

Answer 6

rectangular pyramid has volume V=1/3 WLH

Answer 7

They told us they both have the same L, W, H

Answer 8

D is wrong as you can see it say rectangular pyramid is 3 time the volume of the prism
which not true since we have V=1/3 LWH

Answer 9

Rectangular prism volume formula = L*W*H
Rectangular pyramid volume = (1/2)A*C*H
Now plug a congruent values for example l=2 and w= 1 and H= 2

Answer 10

so it actually a third of the prism

Answer 11

it is 1/3 not 1/2 dear
