Question

1 gallon of paint pour the paint into a paint tray that measures 10 inch wide 10 inch long and 7 cm deep what will happen

Answer 1

1 gallon = 231 cubic inches

7cm = 2.75591 inches ( round to 2.76 )

10 x 10 x 2.76 = 276 cubic inches

there will be more than enough room for the gallon of paint

276-231 = 45 cubic inches of space left over
