option d) none of these

hope it helps ☺️

Answer 2

Given that length (/) of box = 1.5 m Breadth (b) of box = 1.25 m h = 65 cm

Depth (h) of box = 65 cm = m = 0.65 m

l = 1.5 m

b = 1.25 m

Area of sheet required = Area of cuboid - Area of top which is open

Area of cuboid = 2(lb + bh + lh)

= 2(lb + bh + /h) -lb

= 2(lb) + 2(bh) + 2(/h) - lb

= lb + 2(bh) + 2(/h)

= [1.5 x 1.25 + 2 x 1.25 x 0.65 +2 x 1.5 x 0.65 ] m² = (1.95 + 1.625 + 1.875) m²

= 5.45 m²

Hope it helps you dear.
