Question

HELP! Pci below I GIVE MEDALS:)
the front of a metal shed needs to be spray painted. One can of spray paint will cover 20ft^2. If the 8ftX8ft square door is not painted, then how many cans of spray pain will you need to buy

Answer 1

To do the rectangular area its (16*10) - (8*8)

If you want to do the roof triangle, then you have to figure out how high the peak is (h) and then add 1/2*16*h

Divide that number by 20, and that's how many cans of paint you'll need.

Answer 2

ok for the rectangular I got 96 and for the triangle I got 8 now do I add them then divde by 20

Answer 3

Yes, exactly.

Answer 4

s0 I would need 5and half cans

Answer 5

I get 5.2, but since you can't buy half a spray can of paint, I'd guess you'd need to buy 6 cans.

Answer 6

i got that too thanks for your help :)

Answer 7
