Answer:
Can’t rlly see 1-4
Step-by-step explanation:
5:a=12,b=5
a^2+b^2=c^2
144+25=169
c=13
6: a=8, c=10
64+b=100
b=6
7: a=15,c=17
b=8
8:b=40,c=50
a=30
9:b=2,c=4
a=2 root 3
The surface area of the box will be 112 in²

The formula for the surface area is :
, where
length,
width and
height of the rectangular prism
Given in the diagram that, 
So, plugging the values into the formula...

So, the surface area of the box is 112 in²
Each brick is .4 inch and the whole thing is 5.4 inches tall. So the height over the size of each brick will give you the total number of bricks.
5.4/.4
=13.5
13 1/2 and a half bricks were used to make the model.
Hope this helps :)
