#60 ft^3#

Explanation:

The first thing you have to do is convert the 30 inches to feet

In order to do that, you'd divide the amount of inches by 12 (since there are 12 inches in a foot)

So:

#30/12# = #2.5#
(you'd want this as a mixed number though, so its #2 1/2#, which is #5/2#)

So now we know our dimensions in the desired unit (feet)

Since the volume of a rectangular prism is #l*w*h# (#l# being length, #w# being width, and #h# being height), all that has to be done is multiply these three values together!

#5/2 * 8 * 3#

=

#5/2 * 24#

=

#5/2 * 24/1#

=

#(5*24)/(2*1)#

=

#120/2#

=

#60 ft^3#

Don't forget your units!!
And voila, you are done ;)
