2k - 10 = 6
can someone me i can't figure out the answer

Hello ! 
 

Okay so what you do is add 10 to the other side

2k - 10 +10 = 6 + 10

You would get  

2k = 16

Next you divide 16 by 2 which is 8

and that means 8 is equal to k

K = 8

You must find the surface of the block therefore 98187 dived by 5628 = 583m squared
