Atable is going to be painted. how much less surface area of the table will be painted if the underside remains unpainted? length=22in, width=20in, height=1in

length=22in,width=20in, height=1in

Total Surface are of a table = 2(length * width) + 2(width * height) + 2(height * length)

= 2(22*20) + 2(20*1) + 2(1*22) = 880 + 40 +44= 964 square inches

the surface area of underside table is legth * width = 22* 20 = 440

the underside remains unpainted, so we subtract 440 from total surface

964 - 440 = 524 square inches

440 square inches will remain unpainted

524 square inches will be painted
