Copy a formula down a column
20%
When you copy a formula downwards, Excel moves every reference in it down by the same number of rows. =B2*C2 copied into the row below becomes =B3*C3. This is called a relative reference, and it is the default because it is almost always what you want.
That single behaviour is why a spreadsheet scales: a column of five thousand calculations is one formula and one drag.
In D2, multiply the units by the price. Then fill D2 down to D6 so every line has its total.
