Rocky builds a dog house for a friend of his. Rocky is thinking about painting the dog house half blue and half gold.

The rectangular prism shaped dog house is 7 inches wide, 15 inches long, and 20 inches high.

Part One: Find the surface area of the doghouse.

Part Two: How much blue and gold paint does he need?

Surface Area: 1090 inch²

Blue Paint needed: 545 inch²

Gold Paint needed: 545 inch²

Step-by-step explanation:

Is there a door or something? I'm assuming not because you didn't include it in your question.

Surface Area:

(7*15*2) + (15*20*2) + (20*7*2) =

210+600+280=

1090 inch²

If he paints half the doghouse blue and the other half gold then simply divide the surface area by 2:

1090:2=545

He needs 545 inches² of blue paint

He needs 545 inches² of gold paint.
