20/5 = 4 so you can get four raft lengths along the pool length.
8/2 = 4 so you can get four raft widths along the pool width.
In all, therefore, you can get 4*4 = 16 rafts.
DO NOT work out the area of the pool = 20*8 = 160 sq feet
and the area of each raft = 5*2 = 10 sq feet
and then divide 160/10 to get 16 rafts.
That method does work in this particular case but, in general, will not work unless you are prepared to chop up some of your rafts and fit the bits where they will go.
150 x 100 = 15000 sq feet assuming the space is rectangular.

Multiply all three dimensions to get the volume in cubic feet. Then multiply that product by 7.48 to convert to gallons.
Assuming that your 8' pool has a shallow end then you have an average depth of 4'. Apporx. 7200 gal.
1 acre = 43,560 square feet If this plot is rectangular ... its corners are right angles ... then Area = (20 x 1,320) = 26,400 square feet = (26,400 / 43,560) = 0.606 acres(rounded)
Assuming it is rectangular - the usual case - just multiply length x width. The answer is 210 square feet.

150 x 100 = 15000 sq feet assuming the space is rectangular.

A simple rectangular room 20 feet by 18 feet has 360 square feet.
19' x 5' = 95 square feet (if rectangular)
To find a volume of a rectangular prism, use base X Width X height. I'm sorry, but yo have to find the answer yourself.
Multiply all three dimensions to get the volume in cubic feet. Then multiply that product by 7.48 to convert to gallons.
The are is calculated multiplying length by width, so 160 feet would be a room that would have length times width equal 160. For example, a rectangular room that is 16 feet long by 10 feet wide.
89.55 square yards.
A rectangle has 4 faces: 2 long faces and 2 short faces.
