$947.50 - $189.50 = ?<br>Am I not smart or what?
VashaNatasha [74]
<span>   $947.50
</span> - $189.50
_________
$758.00

So, to do this first we start at the far right and go to the left.

   $947.50 - $189.50_________
   $      .00
0-0= 0
5-5= 0

You then bring down the decimal.

   $947.50 - $189.50_________
    $   8 .00
Because you cannot subtract 9 from 7, you borrow one from the number to the left of it and 7 turns into a 17 as 4 turns into a 3. So then, 17-9=8.
         17
   $93-7-.50         -7- = This means the 7 has been canceled out and turned  - $189.50                        into the 17 above _________         8 .00
This happens again with subtracting 3 from 8 in which you take one from the number beside which happens to be 9 and make it 8.

          17
   $8-3--7-.50         -7- and -3- = This means the 7 has been canceled out                                                         and turned into the 17 above 
  - $189.50                        _________    $ 58 .00
So then, 13-8=5. Finally 8-1= 7

   $947.50
 - $189.50
_________
$758.00

What is the surface area of a box that is 20.1 m long, 6.8 m wide and 7.4 m high?
blsea [12.9K]

Answer:

Surface area of the box is =671.48m^2

Step-by-step explanation:

The box is in the shape of a cuboid:

Surface area of the cuboid = 2(L*W+W*H+H*L)

Length(L)=20.1 m

Width(W)=6.8 m

Height(H)=7.4 m

Surface area:

                 2((20.1*6.8)+(6.8*7.4)+(7.4*20.1))\\\\=2(136.68+50.32+148.74)\\\\=2(335.74)\\\\\=671.48m^2\\\\

The surface area of the box is =671.48m^2
