Question

50 POINTS What is the volume of this?

Answer 1

Just for fun, i will do it differently

big rectangular box (including the missing portion) in lower right

= length x width x height

= 3 x 3 x 4

= 36ft^3

"missing" box at lower right = 1 x 3 x 2

= 6ft^3


so the ans = big box volume - missing box volume

= 36 - 6

= 30ft^3

Answer 2

The volume is 30.

You need to subtract the volume of the smaller box from that of the bigger box. It is written as such:
V = (3*3*4) -(2*1*3)
V = 36 -6
V = 30
