For you need the surface area of the bottom part.
all four side are 10*2 in = 20
20*4 = 80
the top and bottom are both 10*10 = 100
100*2 = 200
total = 280 in

The surface area of the top part:
top and bottom both 5*5 = 25
25*2 = 50
all four sides are 5*8 = 40
40*4 = 160
total = 210 in

Because the top and bottom part stand on each other, you count the bottom of the top part double.
Surface area bottom part = 280
Surface area top part = 210
210+280= 490
So it probably would be 490 in.

A certain law firm consists of 4 senior partners and 6 junior partners. How many different groups of 3 partners can be formed in
lina2011 [118]

Answer:100

Step-by-step explanation:

There are ten total people:

10C3

10!/(7!×3!) = 120

Note: but that includes all the cases where there are no senior partners

So firstly let figure out the number of cases where there are no senior partners

because there are 6 junior partners

6C3

= 6!/(3!×3!) = 20

120 - 20 = 100 or the number of possible groups where there is at least 1 senior partner.
