The easiest, non-technical way to think about it is like this:
-- A scalar is a quantity that has a size but no direction.
Those include temperature, speed, cost, volume, distance, etc.
One number is all there is to know about it, and there's no way you can
add more of the same stuff to it that would cancel both of them out.
-- A vector is a quantity that has a size and also has a direction.
Those include force, displacement, velocity, acceleration, etc.
It takes more than one number to completely describe one of these.
Also, if you combine two of the same vector quantity in different ways,
you can get different results, and they can even cancel each other out.
Here are some examples. Notice that in each of these examples,
every speed has a direction that goes along with it. This turns the
scalar speed into a vector velocity.
If you're walking inside a bus, and the bus is driving along the road,
then your velocity along the road is the sum of your walking velocity
inside the bus plus the velocity of the bus along the road.
-- If you're walking north up the middle of the bus at 2 miles per hour
and the bus is driving north along the road at 20 miles per hour, then
your velocity along the road is 22 miles per hour north.
-- If you're walking south towards the back of the bus at 2 miles per hour
and the bus is driving north along the road at 5 miles per hour, then your
velocity along the road is 3 miles per hour north.
-- If you're walking south towards the back of the bus at 2 miles per hour
and the bus is just barely rolling north along the road at 2 miles per hour,
then your velocity along the road is zero.
-- If you're in a big railroad flat-car that's rolling north along the track
at 2 miles per hour, and you walk across the flat-car towards the east
at 2 miles per hour, then your velocity along the ground is 2.818 miles
per hour toward the northeast.

Answer:
The demand forecast for winter is 96.36 millions KWH
The demand forecast for spring is 145.08 millions KWH
The demand forecast for summer is 169.89 millions KWH
The demand forecast for fall is 73.08 millions KWH
Explanation:
Given that,
The demand trend line is
We need to calculate the demand forecast for winter
Using given formula
Put the value into the formula
We need to calculate the demand forecast for spring
Using given formula
Put the value into the formula
We need to calculate the demand forecast for summer
Using given formula
Put the value into the formula
We need to calculate the demand forecast for fall
Using given formula
Put the value into the formula
Hence, The demand forecast for winter is 96.36 millions KWH
The demand forecast for spring is 145.08 millions KWH
The demand forecast for summer is 169.89 millions KWH
The demand forecast for fall is 73.08 millions KWH
You can use the displacement method or the eureka can so basically in the displacement can what you have to do is to put some water into a measuring cylinder and measure its volume before adding the irregular shaped object and then measuring the level of water which had been displaced and then eureka can you can check online
