Question

I need help someone give me the answers

Answer 1

So what you want to do is simply find the volume of each.

`V=lwh`

V: Volume
l: Length
w: width
h: height

So for the first two:


`V= 4*4*1`

`V= 3*3*1`

Then you want to add the volumes of all four together.

Answer 2

It says each one is smaller than the next one so keep subtracting 1
