While estimating you would round the decimals and you would think in terms of how would the answer look like when you multiply 64 with 10...  640ish..and then you think about the decimals a little,,, soyou will put decimal after 64... and that will give you 64.0 or something ...While the exact answer id 65.79... Close enough.

To find the amount of work done, we need to use the formula for work.
The formula is: Force x Distance.
The force being given is 50N, and the distance traveled is 3M.
With this information, we're ready to solve!
Let's plug in our numbers to the formula given above.
Work = 50 x 3
50 x 3 = 150.
The amount of work done is 150J.
I hope this helps!
