What is the volume in cubic centimeters of the cake if the cake shows 3 cmand30cmand20cmmineed to know asap

So we think that this is rectangular prism cake since 3 measures given
volume=legnth times width times height
it doesn't matter which one is legnth widht and height but probably
height=3
legnth=30
width=20

so mutiply
3 times 20 times30=1800
answer is 1800cm^3

$34.24 is the right answer
