Carla has 1 gallon of paint.she is going to pour it into a paint tray measure 10 inches wide 10 inches long an 7cm deep

Well, one gallon is 231 cubic inches. To find the volume of the tray, we need to multiply length by width by height. First we notice that the height is 7 centimeters so we have to convert it to inches. 7 centimeters equals 2.75591 inches. Now we multiply 10*10*2.75591=275.591 which means the tray can hold about 276 cubic inches of paint. Well 231 cubic inches can fit into 276 so the paint will not overflow. Hope this helps!

I predict 74 is the answer. Sorry if I am wrong.
