Surface Area and Materials Calculation

Calculation of Surface Area and Volume
	Length in feet	Width in feet	Height in feet	Surface Area in sq. ft.	Volume in Cubic Feet  l x w x h
Room size	12	10	8		960
Floor	12	10		120
2 walls (long)	12		8	192
2 walls (short)		10	8	160
Ceiling	12	10		120
Total surface area =				592
How to use this information…
What size A/C unit do you need to cool your room?

Note:
1 ton of cooling capacity = 12000 BTU of cooling capacity
600 sq.ft. of living space (w/8' ceiling) requires 1 ton of cooling capacity
How much carpet do you need to buy to cover the floor?
Example:
	Floor Area in sq.ft.	Carpet width in ft.	Price per linear foot	Number of linear feet required

Note:
Calculate linear feet needed to cover the floor of your room….
Price is given in sq.ft. and linear ft.
How many gallons of paint are needed to paint your walls?
Example:
	Area in sq.ft.	Coverage per gallon	Gallons required	Paint price per gal.
	472	400	1.18	$        9.97	$      19.94

Note:
Assume that 1 gallon covers ~ 400 sq. ft.
(120sq. ft. +160 sq. ft.+ 192 sq.ft.) = 472
