**Answer:**

Area of bottom of cuboid = l×b

= 1×2= 2 m²

Total surface area = 2(lb+bh+hl)

= 2(1×2+2×1.5+1.5×1)

= 2(2+3+1.5)

= 2×6.5

= 13 m²

According to the question the bottom of the box is not painted, then

Area of box painted = (Total surface area - bottom area)

Area of box painted = (13 - 2) m² = 11 m².
