for the 2nd one, how do you know the the height for the larger one is 7 cm?
the length of the big block above the small block is 4 cm, the small block is 3 cm high. so the height of the big block is 3 + 4 = 7cm high

what question is that for? anyway, it doesn't matter, that is almost certainly wrong. i don't think any of the problems should be worked out like that. in your formula you have 3 things being multiplied, yet you have 6 multiplication signs, that should tell you that you're doing something wrong
