How to calculate this science equation 10 pts

ok so its

1/2 (0.300kg)(20.0m/s)^2

The answer was 60.0 but when i calculate it its 6. I dont get it i need help step by step again please lol.

20.0 ^ 2 = 400
400 * .3 = 120
120 * 1/2 = 60

Not sure where you're losing the decimal point?

1/2 (0.300kg)(20.0m/s)^2
(0.150kg)*(400m/s) = 60
