Why is work the same pushing an object up an incline vs lifting it vertically?

[sparkle123]

When pushing an object up an incline, isn't work done in the horizontal direction?
But when lifting it direction, no work is done in the horizontal direction.
So why does my textbook say that the work done in both cases is the same? :(

Work done is a scalar quantity. It does not have any direction.
Can you quote the exact paragraph from your book?
