The front of a metal shed needs to be spray painted. One can of spray paint will cover 20 feet squared. If the 8ftX8ft square door is not painted then how many cans of spray paint will you need to buy?

Respuesta :

4 cans of paint. 8*8 = 64 feet squared. 3 won't be enough because 20*3 = 60. 20*4 = 80, so you will have enough
