Question

PLEASE HELP ME! I am using my last points for this question, I have asked three times. Question: I am building a playhouse for my granddaughter. I will need to buy paint for the walls and indoor/outdoor carpet for the floor. The playhouse is 1 room. I am painting only the walls. The walls are 6' high. The playhouse is 10' long and 8' wide. Each can of paint covers 100 sq ft. How many cans of interior paint will I need to buy? Tell me your process for working the problem.

Answer 1

You will need 4 cans of interior paint.

Explanation:

Because the playhouse is rectangular prism, you know there are 6 walls: 2 floor, 2 ceiling, and 2 side. You can use the expression 2(6*8)+2(10*6)+2(10*8). This simplifys to 2(48)+2(60)+2(80), which equals 96+120+160. The sum is 378, and since each can covers 100 square feet, you will need 4 cans, which cover 400 square feet, to cover every wall.

Hope this helped!
