Answer 2

Answer:

Here, l = 1.5 m, b = 1.25 m, h = 65 cm = 0.65 m.

Since the box is open at the top, it has only five faces.

(i) So, surface area of the box = lb + 2(bh + hl)

= 1.5 * 1.25 + 2 (1.25 * 0.65 + 0.65 * 1.5)

= 1.875 + 2 (1.7875)

= (1.875 + 3.575)

= 5.45 m2

Hence, 5.45 m2 of sheet is required.
