L x W x H

18 x 14 x 8

Room Perimeter

P = 2W + 2L

P = 2(14) + 2 (18)

P = 28 + 36

P = 64

Perimeter * Height

P = 64, H = 8

Area to paint = 64 * 8

A = 512 sq ft

512 sq ft/256 sq ft paint coverage = gal of paint needed

512/256 = 2 gals per coat

2 gals/coat * 2 coats = ? ttl gals needed

Gal. needed * 9.50 per/gal = Total Cost

Need to calculate the amount of building and finishing materials that you must purchase for your room. Purchases must include:

Flooring

Wall covering/treatment

Baseboards, casing, trim

Ceiling lighting

In order to calculate these amounts, you must consider the following:

• Your room has the dimensions of 14 feet by 18 feet

• It has a door that measures 30 inches by 78 inches.

• There is one window with the dimension of 36 inches by 24 inches.

Use the following as an example for your coast calculations:

Flooring:

Area of the floor=

Amount of flooring required: _____________________

Choice of flooring: _____________________

Unit cost of flooring: ______________

Total flooring cost: __________________

Mush provide similar detailed cost calculation for the wall coverings/treatment, baseboard/casing/trim and ceiling lighting.
